fix(dashboard): never crash on a malformed reservation date

A reservation with an invalid date blanked the whole My Trips page: the old Upcoming widget did new Date(value).toISOString(), which throws "Invalid time value" (fixed in #1222 by reading the string parts). Also guard splitDate so a bad date renders a dash instead of "Invalid Date" or throwing.
fix(atlas): give every sub-national region a distinct code (#1217 )

 | `HSTS_INCLUDE_SUBDOMAINS` | When `true`: adds the `includeSubDomains` directive to the HSTS header, extending HTTPS enforcement to all subdomains. Only effective when HSTS is active (`FORCE_HTTPS=true` or `NODE_ENV=production`). Leave `false` if you run other services on sibling subdomains over plain HTTP. | `false` |

+| `SESSION_DURATION` | How long a login session stays valid when **"Remember me" is unchecked** (the default): sets the `trek_session` JWT `exp` and issues a browser-session cookie (cleared when the browser closes). Accepts `ms`-style strings: `1h`, `12h`, `7d`, `30d`, `90d`. Invalid values warn at startup and fall back to the default. | `24h` |
+| `SESSION_DURATION_REMEMBER` | Session length when **"Remember me" is ticked** at login: a longer-lived JWT plus a persistent `trek_session` cookie that survives browser restarts. Same format and startup-fallback behaviour as `SESSION_DURATION`. | `30d` |
