Closes the bandwidth-abuse vector on the in-app update flow. Both
endpoints now sit inside the authed.Group; APK additionally gets a
60s/user rate limit to suppress accidental hammering or scripted
abuse.
### Server
- internal/api/client_assets.go:
- clientAPKAllowDownload(): in-memory map[userID]time.Time under
a mutex. Returns 0 (allow) or wait duration (block).
- handleClientAPK reads user from context, checks the limit,
returns 429 + Retry-After header if blocked.
- testResetClientAPKRateLimit() lets tests start clean.
- internal/api/api.go: routes moved from the root /api group into
the authed.Group block (alongside /quarantine, /requests, etc.).
- Tests: added TestClientAPK_401WhenUnauthenticated and
TestClientAPK_RateLimit_429OnRapidSecondCall (also verifies
different user gets a fresh slot). Existing tests updated to use
authedRequest() helper.
### Web
- MobileAppDownload.svelte: switched from bare fetch (no credentials)
to api.get<>() which carries the session cookie. 404 / 401 /
network errors all silently hide the download row.
- Removed the login-page mount entirely — pre-auth surfaces should
never show this. Settings → Mobile app section keeps it for
logged-in users.
Flutter unaffected: dio's Bearer interceptor already attaches the
token, and the polling only fires once the post-login shell mounts
the banner widget.

- flutter analyze: Riverpod 3 dropped StateProvider; replaced
_dismissedVersionsProvider with a small Notifier<Set<String>>
+ NotifierProvider, mutating via an `add(version)` method.
Public API (shouldShowUpdateBannerProvider, dismissUpdateProvider)
unchanged.
- golangci errcheck: defer f.Close() now wrapped in func() { _ = f.Close() }();
os.Setenv calls in test helper switched to t.Setenv (cleaner — auto-restores
on test cleanup, no manual Unsetenv needed).

Phase 1 of the in-app update flow — server side. Endpoints serve the
bundled Android APK + sidecar version file from /app/client/.
Returns 404 gracefully when files aren't present, so dev environments
and pre-CI-wiring images degrade cleanly to "no update available."
- internal/api/client_assets.go: handleClientVersion + handleClientAPK.
Both unauthenticated (matches /healthz) so install flow doesn't
depend on a live session. APK served with proper
application/vnd.android.package-archive Content-Type +
http.ServeContent so Range requests work for resumable downloads
on flaky networks.
- Path resolves to /app/client/ by default; MINSTREL_CLIENT_APK_DIR
env var overrides for dev.
- Dockerfile creates /app/client/ + commented COPY hooks for the CI
sequencing phase.
- Tests cover all four states: missing apk, apk-but-no-version,
both present (200 with correct shape), apk stream (200 with
correct Content-Type + body bytes).
Phases 2 (Flutter client provider + banner + install intent + Android
manifest changes) and 3 (CI sequencing to bake the APK into the image)
land in follow-up commits.
