Each sync run now writes _strava_sync_status.json per user (status,
imported count, error message). New admin endpoints expose this data
and allow triggering an on-demand sync. The admin page gains a Strava
Sync section showing per-user token/credentials state, total imported,
last sync time, and last-run status with inline error messages.
- Add bincio sync-strava command: headless multi-user Strava sync
designed for systemd timer. Discovers users via strava_token.json,
skips users without their own strava_credentials.json, respects
Strava visibility (only_me → unlisted). Treats 404 stream errors as
no-GPS activities rather than retrying every run.
- Add deploy/systemd/bincio-sync.{service,timer}: runs every 3 hours,
Persistent=true to catch up after downtime.
- Add POST /api/internal/rebuild: webhook for sync timer to trigger
site rebuild, authenticated via X-Sync-Secret header.
- Add suspended column to users table with auto-migration on open_db.
Suspended users are blocked at login and session lookup (covers both
activity site and wiki, which share instance.db).
- Add POST /api/admin/users/{handle}/suspend|unsuspend and
DELETE /api/admin/users/{handle}/account endpoints.
- Admin panel: Suspend/Unsuspend toggle, Del account button, suspended
badge on user row.
