fix: 7 bugs — parse_mode, /removeplayer, SNo>300, fd leak, warmup sleep, warmup range, dupe print

- cancel_sub: add parse_mode=MARKDOWN_V2 so users don't see literal backslashes
- /removeplayer: add CommandHandler that was advertised in /start but missing from handlers
- parse_standings: raise SNo limit 300→5000 to support large open tournaments
- call_bbp_with_checklist: close mkstemp fd to fix resource leak
- _warmup_cache_sync: make time.sleep(1.0) conditional on HTTP fetch, skip for cache hits
- _warmup_cache_sync: derive start_tnr from max(max_tnr_seen, max cached tnr) instead of hardcoded 1445000
- main: remove duplicate print('Client bot started') after blocking run_polling()
