tiennm99 c57306119a feat(alias): log the shape of a capture at debug level
The capture failures worth debugging are all about what Telegram did not
deliver: a reply stripped of its content, a caption where text was
expected, or a kind that falls through the switch. None of that is
visible from the user-facing refusal, which only says "unsupported".

One alias_capture line per /alias reports field names, lengths and
counts — never message text, so aliased messages cannot travel with the
logs.
