Fix Plaud integration: use official connector, resolve file_id via list_files

Root cause found: the web app's recording URL slug is missing the 'of_'
prefix the API's real file_id requires — direct lookup by URL id always
404'd regardless of which connector or account. Fixed by resolving the id
via list_files(query=...) instead. Also: stop using the deprecated
'Plaud MCP' connector entirely, use the official 'Plaud' connector only.

Verified live: pulled the 09-16 meeting transcript for real via the
official connector, content matches the manually-uploaded transcript used
to build the first brief. Recap mode's live data path is now confirmed
working end-to-end, not just designed.

+  (`next_cursor`) — loop until it's null before treating the transcript as complete.
+  `get_note` returns the AI summary/action items tab separately from the raw
+  transcript — worth pulling alongside `get_transcript`, not instead of it.
