suspend fun bumpTileValidatedAt(content: GpkgContent, tpudtId: Long, validatedAt: Long): ERROR CLASS: Unresolved name: withContext
Refresh only GpkgTileRevalidation.validatedAt for tile row tpudtId — the 304-Not-Modified path, where the bytes and validators are unchanged but we want the freshness window to restart so the tile isn't re-requested every frame. Read-modify-write preserves the stored ETag / Last-Modified. No-op when the tile has no revalidation row yet.
