Garmin auth/sync routes move under /api/garmin/*; sync.Service becomes
garmin.Sync with garmin.SyncConfig/ClientConfig; applog becomes
internal/log; the test mock moves into the garmin package as MockClient
(breaking the test-only import cycle the merge created); stale test
URLs and type names updated to match.

Replaces every page/component's ad-hoc inline error paragraph with a
shared, module-level banner store (red/orange/blue/green, stacking,
auto-dismiss + manual close) -- from docs/IDEAS.md's backlog item.
