feat(api): expand the public v2 files surface

Adds folder support, rename/restore, move, bulk archive, share, and content
replace to /api/v2/files, so managing files by API no longer stops at
upload + download + archive-one.

Routes are thin: auth -> parse -> perform* -> serialize. Share and content
replace get their orchestration extracted first so the session routes and
the public ones cannot diverge on the effective-authType resolution, the
EE public-sharing gate, or the storage-quota classification.

Presigned upload stays session-only: presign does an advisory quota check
and the real debit happens in the separate register step, so a caller that
never registers leaves unaccounted bytes with no reaper. The buffered
multipart path debits inside uploadWorkspaceFile's own transaction.
