Add chat actions, channels/groups mgmt, directory + deadmans bots, network status

Profiles/bots (profiles.py, main.py):
- Surface real send errors; fix group send and member-count staleness (refresh on view)
- Group/channel actions: join, leave, owner delete; consistent member counts
- Contacts: always-visible Chat, plus Clear chat and Delete contact
- Support bot: OpenAI-compatible LLM backend (Grok/Ollama/OpenAI) per-bot config
- Deadmans bot: check-in window, trigger message, recipients, owner
- Directory bot: add-to-group registration, super-user /approve /reject /list, search,
  publishes listing.json in the website schema (directory.py registry module)
- Profile edit (name/bio/avatar) + avatars on list pages
- Global status + /network page (operators, SMP/XFTP servers) and Settings network info

UI (templates):
- Chat rooms; collapsible left sidebar with notifications + network widget
- Per-directory-bot website generated on creation (name substituted)
- Matrix theme; copy/hyperlink addresses; site footer

Ignore runtime bot state and generated directory sites.
