Walkthrough

This PR adds map-driven auto-fill of elevation and country code in the location form by querying invisible MapLibre vector layers on marker placement. It also introduces a shared time-helpers.ts module (with tests) and refactors FlightForm to use it, improving default initialization, reactive landing-time clamping, and IGC field overwrite behavior. Separately, a GHCR publish workflow and Synology docker-compose are added.

Changes

Map-Driven Elevation & Country Lookup

Layer / File(s)	Summary
BaseMap: vector layers, lookup functions, and marker trigger frontend/src/lib/components/BaseMap.svelte	Adds a minimum-zoom constant, two exported callback props (onElevationLookup, onCountryLookup), internal functions that query rendered terrain-contour and country-boundary features, marker-update hooks that call those functions, and two invisible fill layers loaded only when editable is true.
SingleMap: prop forwarding frontend/src/lib/components/SingleMap.svelte	Adds the two new optional callback props to SingleMap's public API and passes them through to BaseMap.
LocationForm: handlers, hint UI, wiring, styles, and translations frontend/src/routes/locations/LocationForm.svelte, frontend/src/translations/en/translation.json, frontend/src/translations/de/translation.json, frontend/src/lib/components/map.ts	Adds showElevationHint state and two handler functions, wires them to SingleMap, renders a conditional zoom-in hint near the elevation field, adds CSS for the hint container, and adds hint--zoom-in-elevation strings in English and German. Updates the Mapbox access token.

Time Helpers Module & FlightForm Refactor

Layer / File(s)	Summary
time-helpers.ts: new utility module and tests frontend/src/lib/time-helpers.ts, frontend/src/lib/time-helpers.test.ts	Introduces timeToMinutes, minutesToTime, hmsToTime, calculateFlightDuration, ymdToDateString, and isTimeBefore with full Vitest coverage including boundary values, rounding, midnight crossing, and leap-year cases.
FlightForm: import replacement, initialization, reactive clamping, and IGC overwrite frontend/src/routes/flights/FlightForm.svelte	Replaces local time helper imports with shared utilities, auto-fills today and 00:00 for new flights, adds reactive logic that advances landingTime when it would precede launchTime, delegates duration to calculateFlightDuration, removes the local hmsToTimevalue helper, and changes IGC processing to always overwrite date/time/site/distance fields.

Deployment Infrastructure

Layer / File(s)	Summary
Secret key config, GHCR publish workflow, and Synology docker-compose .env, .github/workflows/publish-ghcr.yml, docker-compose.synology.yml	.env gains a ROCKET_SECRET_KEY placeholder with generation guidance. The GHCR workflow reuses existing test jobs, then builds and pushes the Docker image. The Synology docker-compose defines three services (db with healthcheck, api pulling from GHCR, web using Nginx) and a frontend-static named volume.
