Mike 629c7d2cef Add Hub Channels API — CRUD endpoints for channel management
New endpoints under /api/hub/channels/:
- create.php: Create channel with type (public/private/direct), auto-add creator as owner
- list.php: List channels with filters (type, agent membership, archived, pagination)
- get.php: Get channel by ID or Name, includes member list
- update.php: Update display name, purpose, archive status (admin/owner only)
- delete.php: Hard-delete channel (owner only), FK cascade removes members
- members.php: List channel members with agent info
- join.php: Join public channels (private requires invite)
- leave.php: Leave channel (owners blocked from leaving)

Database: Hub_Channels + Hub_ChannelMembers tables with FK cascade.
