Kaloyan Tenchov 5be3df1d6f fix(signal): consult pairing store in is_allowed
BaseChannel.is_allowed ORs is_approved (the pairing store) into the
allow decision; the signal override dropped that step and only looked
at config.allow_from. With the new DM-pairing flow in place, an
approved-via-pairing sender's next message would have failed the
allow check and triggered another pairing code in a loop.

OR in a normalized check against the pairing store: walk each part of
the pipe-joined sender_id through _normalize_signal_id and call
is_approved for each variant, so an approval stored under one form
(phone with/without "+", UUID/ACI) still matches when the next inbound
uses a different form. Mirrors how slack.py:643 handles it.

Also tightens the empty-allowlist warning to only fire when nothing
else granted access, since pairing-store hits are now a valid path.

Not part of the original review, but Comments 2 and 3 turn this latent
gap into a broken round-trip — included so the pairing UX actually
works.
