fix(stage-328): backfill #1981's 17 new kanban keys into zh-Hant locale

PR #1979 (@Michaelyklam) backfilled the existing kanban keys into zh-Hant
which was the missing locale block.  PR #1981 then added 17 NEW kanban
keys (edit_task, run_dispatcher_confirm, assignee_profiles_label,
dispatch_* result fields, etc.) but only to the 8 existing kanban-supporting
locales — zh-Hant was again left without those new keys.

This commit closes the gap fully: the 17 new keys from #1981 now exist in
zh-Hant too, with Traditional Chinese translations adapted from the
Simplified Chinese (zh) versions in the same file.

Without this commit, zh-Hant users would have:
  - The full create-task modal localized (from #1979 + #1965)
  - But the new edit-task / run-dispatcher / assignee-dropdown / dispatch
    result strings falling back to English

Adapted translations preserve the same shape and tone as the zh block.
The gap is mechanical (translation drift, not architectural) and worth
closing inline rather than leaving as another follow-up issue.

JS syntax: clean (`node -c` on i18n.js + panels.js).
Kanban tests: 34/34 pass on this stage.
