refactor(drafts): extract DraftEditorModals trailer block

The four editor routes (scripts/flows/apps/apps_raw) mounted an
identical pair of trailer modals — DraftSyncConflictModal +
OtherUsersDraftsModal — wrapped in the same guard chain and {#key path}
remount. Lift the markup into one component; routes thread their
itemKind, path, editPathFor, and loader callback.

Pure markup extraction, no state ownership change. Drops the unused
userStore import where the trailer was the only consumer.

+	 * The two modals every editor route mounts at its trailer:
+	 *  - DraftSyncConflictModal: surfaces a 409 from the autosave pipeline.
+	 *    The route supplies `onLoadFromServer` (re-fetches the deployed-overlay
+	 *    response and re-seeds editor state) and a `getLocalDraft` getter that
+	 *    snapshots the cell value for the overwrite branch.
+	 *  - OtherUsersDraftsModal: surfaces the list of other workspace users (or
+	 *    the legacy NULL-email row) with a draft at the same path, offered for
+	 *    forking. Open-gated on `otherDraftsUsers.length > 0`.
+	 *
+	 * Gates the whole block on `enabled` (defaults to true) — the scripts
+	 * route uses this to suppress when viewing a specific hash.
+	 *
+	 * Wrap the OtherUsersDraftsModal in `{#key path}` so navigating between
+	 * editor paths fully remounts the modal (carrying its `jsonOpen` /
+	 * fork-target state with it) instead of trying to recompute its
+	 * `forkPath` derivation for a new path mid-flight.
