feat(cursor): adds local-only manual refresh route

Adds POST /api/providers/[id]/refresh-cursor, a dedicated
loopback-only route that calls the renewal orchestrator on demand
for a single Cursor connection, bounded by a 30s per-connection
cooldown. Classifies the new route in LOCAL_ONLY_API_PATTERNS and
closes the manage-scope-bypass gap for dynamic-segment spawn-capable
routes under /api/providers/ via a new SPAWN_CAPABLE_PATTERNS /
SPAWN_CAPABLE_PATTERN_ANCESTORS mechanism, which also retroactively
covers the pre-existing /login route. The existing shared
/api/providers/[id]/refresh route is untouched and stays
remote-reachable for every other provider.
