fix(mcp): correct UTC drift in recording-policy tool descriptions + list missing tools

Two real wire-check findings:

1. get_camera_recording_policy and set_camera_recording_policy still
   said "HH:MM, UTC" / "HH:MM 24-hour UTC" in their tool descriptions.
   Per-org timezone shipped in v0.1.43 — windows are interpreted in the
   org's configured timezone, not UTC. An AI agent reading the old
   description would convert wall-clock "8 AM Pacific" to "16:00" and
   write the wrong window. Both now say "interpreted in the org's
   configured timezone (NOT UTC) — pass exactly what the user said, do
   not convert." Also surfaced the modes_conflict invariant in the set
   description so the AI knows the error shape ahead of time.

2. McpPage public-facing TOOLS list was missing five tools that are
   actually live: list_incidents, get_incident, get_incident_snapshot,
   get_incident_clip (read), and attach_clip (write). Backed-into the
   list during the wire check after grepping every @mcp.tool(name=...)
   registration against the array.

Wire check verified end-to-end against prod: 23 registered tools, all
in the gating frozensets, 16 live-tested with real responses
(view_camera returned a JPEG, get_incident_snapshot returned the
previously stored evidence image, set_camera_recording_policy correctly
422'd on the mutual-exclusion path with {error:"modes_conflict"}).
