style(native): format the in-app purchase files and strings

feat(native): TREK Cloud subscriptions through the App Store
The plan picker sent buyers to the website, which the App Store does not allow. It now sells through StoreKit 2 in the TrekShell plugin (feature storeKit): App Store price strings in the buyer's currency, the purchase sheet, the signed transaction redeemed at the control plane, and the transaction finished only once the instance exists. A purchase whose redeem failed is redeemed again on retry, never bought twice. Restore purchases, the auto-renewal terms and the links to the terms of use and the privacy policy sit under the plans. Where no store purchase is possible (Android, an older binary) the picker shows the plans with no way to buy and no pointer to the web.

 name: Native apps release
 # Builds the signed store builds of the iOS and Android apps and uploads them:
 # the Android App Bundle to a Google Play testing track, the iOS archive to
 # App Store Connect (TestFlight). Promotion to production stays a manual step
 # in both consoles.
 #
 # Runs only in liketrek/TREK, only by hand or on a version tag, and only after a
 # required reviewer approves the `store` environment, which holds every secret
 # (see wiki/Native-Apps.md for the list). Pull requests never reach it.
 #
 # Both stores get the same numbers: the version from client/package.json
 # without a prerelease suffix, and a build number that only grows. A prerelease
 # reuses its X.Y.Z with a higher build number and belongs on the internal track
 # and in TestFlight only.

 - `COOKIE_SECURE` is auto-derived (on when `NODE_ENV=production` or `FORCE_HTTPS=true`). Set `env.COOKIE_SECURE: "false"` only during local testing without TLS. **Not recommended for production.**
 - Web Push needs no chart settings: TREK generates its key pair on first start and keeps it in the database on the data PVC. To bring your own pair, set `env.VAPID_PUBLIC_KEY` and `secretEnv.VAPID_PRIVATE_KEY` together (and optionally `env.VAPID_SUBJECT`); changing the pair later means every device has to turn push on again.
 - Set `env.OIDC_DISCOVERY_URL` to override the auto-constructed OIDC discovery endpoint. Required for providers (e.g. Authentik) that expose it at a non-standard path.
- `podSecurityContext` defaults to `fsGroup: 1000` with `fsGroupChangePolicy: OnRootMismatch`, and `securityContext` (the container's) is empty. The container then starts as root, hands any file under `/app/data` and `/app/uploads` that is not owned by `node` yet to `node`, and drops to `node`. To run as `node` from the start, for example under the `restricted` Pod Security Standard, set `podSecurityContext.runAsUser: 1000` and `runAsGroup: 1000`; the image then skips that step and the privilege drop. See the example in `values.yaml`.
+- `podSecurityContext` defaults to `fsGroup: 1000` with `fsGroupChangePolicy: OnRootMismatch`, and `securityContext` (the container's) is empty. The container then starts as root, hands `/app/data` and `/app/uploads` to `node` (uid 1000) if the directory or anything directly inside it is not owned by `node` yet, and drops to `node`. Deeper files are not checked. Only the owning user is changed (plus a `root` group), so a different `fsGroup` stays in place. A volume that refuses `chown` (NFS with `root_squash`) logs a warning instead; set `runAsUser: 1000` then.

 <!--
  TREK is self-hosted: the user points the app at their own server, so we cannot
  know its scheme or its certificate authority ahead of time. Two deliberate
  relaxations, both required for that to work at all:
  1. cleartextTrafficPermitted="true" — Android blocks http:// by default from
     targetSdk 28 on. A bare LAN server (http://192.168.1.10:3001) and a
     Tailscale host (100.64.0.0/10, which is NOT RFC1918, so a private-range
     allowlist would not cover it) both need this. https:// is unaffected and
     remains the recommended setup.
  2. <certificates src="user" /> — since Android 7 apps ignore user-installed
     CAs unless they opt in. Self-hosters running their own CA (step-ca, mkcert,
     an internal PKI) install its root on the device; without this the app would
     reject their perfectly valid https:// server. System CAs stay first so
     public certs keep validating normally.
  The tradeoff is that a user-installed CA can also be a MITM proxy's. That is
  the same tradeoff the browser-based PWA already makes, and it is the price of
  letting people run their own infrastructure.

 #   Gradle start up script for POSIX generated by Gradle.
 #
 #   Important for running:
 #
 #   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
 #       noncompliant, but you have some other compliant shell such as ksh or
 #       bash, then to run this script, type that shell name before the whole
 #       command line, like:
 #
 #           ksh Gradle
 #
 #       Busybox and similar reduced shells will NOT work, because this script
 #       requires all of these POSIX shell features:
 #         * functions;
 #         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
 #           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
 #         * compound commands having a testable exit status, especially «case»;
 #         * various built-in commands including «command», «set», and «ulimit».
 #
 #   Important for patching:
 #
 #   (2) This script targets any POSIX shell, so it avoids extensions provided
 #       by Bash, Ksh, etc; in particular arrays are avoided.
 #
 #       The "traditional" practice of packing multiple parameters into a
 #       space-separated string is a well documented source of bugs and security
 #       problems, so this is (mostly) avoided, by progressively accumulating
 #       options in "$@", and eventually passing that to Java.
 #
 #       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
 #       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
 #       see the in-line comments for details.
 #
 #       There are tweaks for specific operating systems such as AIX, CygWin,
 #       Darwin, MinGW, and NonStop.

 # iOS release signing and TestFlight upload, driven by .github/workflows/native-release.yml.
 #
 # Automatic signing cannot work on a CI runner with no registered devices: it signs
 # the archive for development and then needs a development provisioning profile, which
 # requires a device. So this signs manually for distribution instead. The distribution
 # certificate and the App Store provisioning profile are created (or reused) through the
 # App Store Connect API key, which means no certificate or profile has to be stored as a
 # secret: the key the workflow already holds is enough.
 #
 # The lane expects these in the environment (the workflow sets them):
 #   ASC_KEY_ID, ASC_ISSUER_ID, ASC_KEY_PATH  — the App Store Connect API key
 #   APPLE_TEAM_ID                            — the developer team
 #   MARKETING_VERSION, CURRENT_PROJECT_VERSION — the version and build number
 #   RUNNER_TEMP                              — a writable scratch directory
