chengyongru 4e7022e73c refactor(pairing): apply simplify review fixes
- Extract format_pairing_reply() and format_expiry() to eliminate
duplication between BaseChannel and SlackChannel.
- Use _write_text_atomic() from helpers.py instead of hand-rolled
fsync logic in pairing store.
- Convert approved lists to in-memory sets for O(1) lookup.
- Remove collision retry loop (8-char entropy is sufficient).
- Fix /pairing command parsing to split prefix exactly.
- Remove unused import time from base.py.
- Fix tests to pass subcommand_text, not full /pairing string.
