- List all orb_gainers_*.yaml configs via GET /orb-scanner/strategies (reads _meta.name)
- _get_params() now accepts strategy_id with per-strategy dict cache
- exit_check() replaces hardcoded stop constants (0.75/0.6/0.2/1.0/1.5) with params fields
- check() and gainers_scan() accept optional strategy param
- Frontend: strategy dropdown in page header (localStorage persisted)
- Position.strategy locked at add-time so exit checks always use entry-strategy params
