remove the telegram and whatsapp channels, reduce discord to notifications

All three existed to drive the platform from a chat app. The phone app does that now, so
they are dead weight — three bot gateways, three command parsers, account pairing, admin
config screens and bot tokens sitting in the database.

Gone entirely: telegram/ and whatsapp/, discord/'s bot and command handler, the shared
channel plumbing they were the only users of (pairing.ts, send-and-await.ts, types.ts,
routes.ts and its 20 config/pairing/status endpoints), the six settings components, and
their sections in the integrations screen.

What Discord keeps is the one piece worth keeping — pushing a message out — as
notify/discord.ts, configured by DISCORD_WEBHOOK_URL in the env. No UI, no pairing, no
stored credential, and it never throws: a notification that fails to send is logged and
dropped. Unset means notifications are silently skipped, which is the default state.

Kept deliberately: send-claude-code.ts and send-opencode.ts. They live under channels/ but
have nothing to do with chat apps — they are how /chat and the pipeline executor drive an
agent turn.

Also drops four dependencies with no remaining importer (discord.js,
node-telegram-bot-api, whatsapp-web.js, qrcode), and the /sync-now route added to the email
sidecar an hour ago, whose only consumer was the channel handlers.

The "Channel Models" settings section stays, with its description corrected — it is keyed
off the general access policy rather than anything channel-specific, so it governs non-owner
accounts, not chat apps. Whether that whole class still earns its place is the open
question already noted against origin-validation.

Not touched: the telegram, whatsapp and discord rows in server_integrations, which still
hold their bot tokens. Deleting rows is a different kind of decision and the SQL is in the
handover.
