fix(portable): Gemini keys, Telegram pairing UI, and config durability

Improve first-run and channel setup for non-technical users: detect newer
Gemini key formats, pin Node 22.22.3, add Control Panel Telegram approve
flow, and keep channels/models when config is rewritten. Persist uclaw
wizard state via uclaw-meta.json so restarts skip language/persona prompts.
