A user who tapped Always on an approval button gets a pairing-store entry.
_is_user_authorized() checked the pairing store BEFORE the allowlist and
returned True unconditionally, so a paired-but-not-allowed user permanently
bypassed TELEGRAM_ALLOWED_USERS (or equivalent) even after being removed from
the allowlist (#23778).
Record pairing membership but only honor it in the no-allowlist branch. When
an allowlist IS configured, the paired user must appear in the canonical
allowed_ids set (the same set that resolves WhatsApp aliases, SimpleX names,
group allowlists, and the '*' wildcard), so pairing grants no extra access.
Cherry-picked/rebased from #47736 (#23805) by ygd58; membership check rewritten
to reuse the existing allowlist logic. Adds regression tests.
