fix(pres_mgmt): remove lock_config — sync is now fully unconditional

lock_config made roughly half of sync_config__event_pres_mgmt()'s fields
conditional: they only updated in a given browser if lock_config happened
to be true at the exact moment that browser last synced. A field's local
value therefore depended on the history of saves, not the current setting
— undebuggable from the UI, and easy to corrupt by toggling Lock Config
off even briefly during testing. This was the actual root cause of the
"POC column / Hide POC sometimes works" reports.

Checked the DB: every event, old and new, already had lock_config: true.
The "unlocked, per-browser preference" use case it was built for has
never actually been used in practice.

- Removed lock_config from PressMgmtRemoteCfg, PresMgmtLocState, the
  sync function (no more conditional block — every field syncs
  unconditionally now, same as labels/Require Agreements always did),
  and the Config page UI (no more System section)
- Old DB records with a lock_config key are simply ignored, same as any
  other removed key — no migration needed
- Moved the now-fully-orphaned ae_comp__event_settings_pres_mgmt_form.svelte
  to ~/tmp/agents_trash (zero imports anywhere; the settings page already
  links to the canonical Config page) — completes Step 5 from the
  cleanup doc
- Marked PROJECT__AE_Events_PressMgmt_Config_Cleanup.md complete — all
  Implementation Steps and known regressions resolved
