Alexandre Brandizzi 44e96cf2a3 fix(media): apply the SH-116 media contract to every upload surface
Photos up to 10 MB (JPG/PNG/HEIC), videos up to 100 MB and 90 s (MP4/MOV),
at most 10 photos and 3 videos per work order, pre-validated with stable
generic messages on the Photos & Videos modal, the Completion Doc media tab,
Extra Docs and the vendor portal. Video duration is read from metadata when
the browser can; unreadable metadata never blocks. Mobile MIME variants
(empty type, octet-stream with a video extension, QuickTime) stay accepted.
The signed completion PDF keeps its 50 MB cap.
