ppfeiffer 9a2753de73 Implement B-protocol forwarding to OpenBCM 
Adds bidirectional bulletin/mail forwarding between the BBS and an
OpenBCM-compatible remote BBS using the FBB B-protocol over AX.25.

Changes:
- ax25/frame.py: add build_ax25_sabm_frame() and build_ax25_disc_frame()
  as command-frames with C-bit and P-bit set
- db/database.py: non-destructive schema migration (_add_column_if_missing),
  bid/forward_pending/forwarded columns on bulletins+mail, new forward_bids
  table, and 7 new forwarding methods (bid_exists, record_bid,
  get_pending_*_for_forward, mark_forwarded, store_forwarded_*)
- bbs/forward.py: new ForwardSession class with full B-protocol FSM
  (IDLE→CONNECTING→BANNER_WAIT→EXCHANGING⇄RECV_BODY→DISC_SENT→DONE)
- bbs/engine.py: route UA/I/DISC/DM frames to ForwardSession before
  user-session handling; add start_forward_session(); extend active_sessions
- bbs/scheduler.py: new ForwardScheduler with thread-safe trigger() for
  periodic and on-demand forward runs
- config.yaml: new forward: block with all configuration options
- main.py: run transport and scheduler concurrently via asyncio.gather()
- web/app.py: GET /api/forward/status and POST /api/forward/trigger routes
