feat: batch consecutive file-edit tool calls into single UI block

Add edit-file batching in ChatView groupedMessages that consolidates
consecutive editedExistingFile, appliedDiff, newFileCreated,
insertContent, and searchAndReplace asks into a single BatchDiffApproval
block. Move batchDiffs detection in ChatRow above the switch statement
so it applies to any file-edit tool type.
