fix: handle application/octet-stream for .gpx on Android 16 (Google Files)

Google Files uses application/octet-stream for .gpx because Android 16's
MimeTypeMap has no entry for that extension. The ExternalStorageProvider
content URI encodes the full file path, so pathSuffix=".gpx" keeps the
ACTION_VIEW filter targeted without matching all binary files.

ACTION_SEND (share sheet) filters added for typed MIME variants; code now
handles both actions — EXTRA_STREAM for SEND, intent.data for VIEW.

For octet-stream and generic XML types, OpenableColumns.DISPLAY_NAME is
checked before parsing (uri.lastPathSegment is an opaque ID for content
URIs, not the filename). All decisions logged to NavLogger.
