perf: SQL LIKE query instead of Python loop; skip warmup if cache >1000

- _build_table_rows: filter to ±5 boards around player
- Normalize names (strip commas) for matching FIDE vs pairings format
- Highlight subscribed player with ✅ emoji
- Reduce name column width to compensate for emoji
- Add tournament name to pairing header
- Manual URL flow: look up subscription to highlight player
- Fix MarkdownV2 escaping for em-dash
