Add Telegram answer learning: poller + applier safety net

- New lib/telegram_answers.mjs: shared module that polls Telegram getUpdates,
  matches replies to needs_answer jobs, saves to answers.json, flips job to new
- telegram_poller.mjs: lightweight cron script (every minute via OpenClaw)
- Applier also processes replies at start of each run as safety net
- sendTelegram now returns message_id, stored on job for reply matching
- User replies "ACCEPT" to use AI answer, or types their own
- Answers persist in answers.json and apply to ALL future jobs
- Also includes: selectOptionFuzzy, multiple dialog handling, browser
  recovery, answers reload, per-job timeout bump to 10min
