feat(maint+ai): OTP modal agent picker + supervisor AI quick actions

Maint shortcuts (Unlock Agent / Force Ready) used to read agentId from the CC-agent's localStorage config — supervisors had no such config and the endpoint 400'd. New flow: after OTP passes, modal calls /api/maint/session-status and renders a two-bucket picker (Locked selectable / Free informational 'Already free'). Orphan locks surface with an explicit label.

- use-maint-shortcuts: agentPickerEndpoint flag on forceReady + unlockAgent
- maint-otp-modal: two-phase — OTP gate, then picker, then submit; OTP
  held in state across phases so the operator doesn't re-enter it

AI chat panel: supervisor context now shows supervisor-appropriate quick actions (Agent performance / Call summary / Campaign stats / Who needs attention?) that map 1:1 to the supervisor tool set on the sidecar. Agent flow keeps the theme-token quick actions (doctors/clinics/packages).
