feat(filebrowser): add delete button to toolbar, fix FAT32 delete/rename with raw sector scanning

- Add SYM_TRASH toolbar button wired to fb_delete_cb (was missing entirely)
- Filter '.' and '..' entries in fb_collect_cb so they never appear
- Rewrite deleteFile/deleteDir/renameFile to use raw sector scanning
  instead of getDirEntries linked-list indices (fixes  gap mismatch)
- Handle root directory correctly (use bootRecord^.rootCluster instead
  of assuming entry 0 is '.')
