Comments were deriving their edited state from the document modified timestamp, so reaction changes surfaced as Edited. This change introduces an explicit content-edit timestamp for GP Comment and drives the UI from that field instead of generic document mutation time.

• Backend: explicit edit tracking

  • Added edited_at to GP Comment.
  • Set edited_at only when content changes on an existing comment.
  • Left reaction updates on normal document saves without treating them as content edits.

• UI: edited state reflects content changes only

  • Switched the comment header Edited label to use comment.edited_at.
  • Switched Revisions visibility to the same field, so revision affordances only appear after a real content edit.

• Data fetch/types

  • Included edited_at in comment list queries and GPComment typings so timeline consumers have the new source of truth.

• Migration

  • Added a backfill patch that derives edited_at from Version rows where the content field changed.
  • Registered the patch under gameplan/gameplan/doctype/gp_comment/patches/ and updated patches.txt to the new module path.
