refactor(video): unify the drill-down JPEG data-URI prefix with the shared contract

Browse Source 
Drops videoBridgeDrilldown's local JPEG_DATA_URI_PREFIX constant in favor of the
exported JPEG_FRAME_DATA_URI_PREFIX from videoBridgeFrameContract, matching the
contact-sheet and dedup call sites. Literal value and all validation semantics
(decodeCanonicalJpeg, the chars bound, timestamp/cap/ordering rules) are unchanged.
