* 🐛 Add accumulated storage byte quota for media uploads
Add media-storage-bytes-per-team quote to prevent persistent DoS via
repeated uploads. The quota sums storage_object sizes from both
file_media_object (media + thumbnails) and team_font_variant
(otf/ttf/woff1/woff2). Default limit is 20 GiB per team, configurable
via PENPOT_QUOTES_MEDIA_STORAGE_BYTES_PER_TEAM.
The check is invoked in upload-file-media-object before processing,
looking up the team-id via file -> project -> team_id join.

* 🐛 Fix deduplicated storage overcounting in media-storage-bytes-per-team quote
The SQL query sql:get-media-storage-bytes-per-team used UNION ALL
across six SELECT branches that each produce a so_id reference.
When deduplication causes multiple file_media_object or
team_font_variant rows to point at the same storage_object, UNION ALL
counts that objects size once per reference — inflating "used bytes"
and causing false :max-quote-reached rejections.
Change all five UNION ALL to UNION so that duplicate so_id values are
collapsed before the JOIN storage_object / SUM(so.size).
Add a test (media-storage-bytes-quote-deduped) that creates one
storage_object referenced by two file_media_object rows and asserts
the computed usage reflects the deduplicated physical size, not 2x.
