CMMS fork: AI bridge reads the project from IndexedDB, not the globals

Console showed buildProjectView reporting "4 photos" but NO
buildProjectImages line at all - it was hitting the silent
`!bomImages.length` early return. The studio.js bomData/bomImages
globals get transiently emptied while a project loads / auto-stitches,
and the get-buffer handler's `await` between buildProjectView and
buildProjectImages is enough of a yield to catch that window.

- buildProjectView + buildProjectImages + applyProjectPatch now call
  db.getComponents/getImages/getNets(currentBomId) directly instead of
  reading bomData/bomImages/bomList.
- buildProjectImages traces on entry ("start (board: ...)") and after
  the DB read ("N image record(s)") so an empty result is never silent.
