Add repair notes journal with running feed, visibility, and status tagging

New repair_note table for timestamped journal entries on tickets. Each
note captures author, content, visibility (internal or customer-facing),
and the ticket status at time of writing. Notes display as a running
feed on the ticket detail page with newest first. Internal notes have
a lock icon, customer-visible notes highlighted in blue. Supports add
and delete with appropriate permission gating.
