docs: add full wiki with 74 pages, assets, and CI workflow

Adds the complete TREK documentation wiki covering installation,
trip planning, admin panel, MCP/AI integration, addons, and operations.

Also fixes encrypt-at-rest gaps: mapbox_access_token, Synology
credentials, per-user webhook/ntfy tokens, and photo passphrases
are now rotated by migrate-encryption.ts and stored encrypted via
settingsService.

+# Journey Journal
+
+Journey is a photo-first travel journal. Each journey is linked to one or more of your trips and contains per-day entries with text, photos, mood, and weather.
+
+> **Admin:** enable Journey in [Admin-Addons](Admin-Addons).
+
+<!-- TODO: screenshot: journal entries view with photos and mood indicators -->

+
+## What Journey is
+
+Journey lets you write a narrative account of your travels alongside your trip plan. Entries are tied to specific days and can include prose, photos, a mood rating, weather conditions, and verdict cards. Completed journeys can be shared publicly with a read-only link.
+
+## Accessing Journey
+
+When the admin has enabled the Journey addon, a **Journey** entry appears in the main navigation. The Journey list page shows all your journals as cards with cover images, entry counts, photo counts, and place counts.
+
+## Creating a journey
+
+From the Journey list, click **Create journey**. Give it a title and optional subtitle, then select one or more existing trips to link. Linking a trip imports the trip's places as location anchors for your entries. You can link additional trips later from the journal settings.
+
+## Journal entries
+
+Each entry corresponds to a day in your journey. The entry editor provides:
+
+- **Title** — a short heading for the day.
+- **Story** — free-form text that supports Markdown formatting.
+- **Mood** — choose one of four values:
+
+  | ID | Label | Color |
+  |---|---|---|
+  | `amazing` | Amazing | Pink |
+  | `good` | Good | Amber |
+  | `neutral` | Neutral | Grey |
+  | `rough` | Rough | Violet |
+
+- **Weather** — choose one of six values: Sunny, Partly cloudy, Cloudy, Rainy, Stormy, Cold.
+- **Photos** — attach photos to the entry. The first photo becomes the card thumbnail in list views.
+- **Pros / Cons** — optional verdict cards. Add items to a **Pros** list (thumbs-up) or a **Cons** list (thumbs-down) to summarise what you loved or what could have been better. These are stored in the `pros_cons.pros` and `pros_cons.cons` arrays on the entry.
+- **Tags** — free-form labels (e.g. "hidden gem", "best meal").
+- **Location** — pin the entry to a map location.
+- **Time** — optionally record a time of day for the entry.
+
+## Mobile timeline
+
+On mobile, entries are displayed in a horizontal scrolling timeline of card thumbnails. Tap a card to open the full entry view in a modal sheet. Each card shows the entry's first photo (or a placeholder pin), date, day number, mood icon, and weather icon.
+
+## Map view
+
+The journey detail page includes a map on the right (desktop) or an integrated map-timeline (mobile) showing all entry locations alongside the places from linked trips.
+
+## Public sharing
+
+You can share a journey with a read-only public link. When creating the link you can independently toggle which sections are visible to visitors: **Timeline** (entries and stories), **Gallery** (photos), and **Map**. Visitors can only see the sections you have enabled, and no TREK account is required. See [Public-Share-Links](Public-Share-Links) for details on the separate journey share token mechanism.
