fix(telegram): resume typing indicator after inline approval click (#27853)

The text /approve and /deny paths in gateway/run.py call
resume_typing_for_chat() after resolve_gateway_approval() succeeds, but
the Telegram inline-button (ea:*) callback in _handle_callback_query did
not. Typing is paused when the approval is sent (gateway/run.py:15658),
so without a matching resume the typing indicator stayed gone for the
remainder of a long-running turn after a button click.

Symmetry-match the text path: after a successful resolve, call
self.resume_typing_for_chat(str(query_chat_id)). Guarded by count > 0
to match /approve's "if not count" early-return — if nothing was
actually resolved, the agent thread was never unblocked, so typing
should remain paused.
