Phase 2b: backend services, routes, and notification triggers

Attachments: multer-backed uploads with random-hex filenames,
streaming downloads with Content-Disposition, 25MB limit,
mimetype allowlist, audit entries, orphan cleanup on DB failure.

Full-text search: searchTicketIds + searchComments via raw SQL
ranked with ts_rank, composable filters via Prisma.sql/join,
hydrated with findMany and reordered via Map to preserve rank.

Pagination: listTicketsPaged returns {data,total,page,pageSize}
only when page/pageSize present (array response stays default,
so the Goddard n8n flow is unchanged).

Bulk actions: reassign/close/setSeverity/setStatus on POST /bulk,
writes one audit entry per ticket via createMany.

Analytics: summarize(window) runs 5 parallel groupBy + raw-SQL
queries for open-by-severity, status counts, queue load,
age buckets, percentile_cont median resolution hours.

CSV export streams matching tickets via res.write; saved views
CRUD with per-user ownership checks (403 cross-user, 404 missing).

Notifications: in-app Notification rows gated by prefs, email via
nodemailer (SMTP_HOST-gated, no-op when unset), outgoing webhooks
with HMAC-SHA256 signed POST and 3-retry exponential backoff.
Triggers wired into createTicket/updateTicket/addComment; mention
detection via parseMentions skips self-notify.

Infra: docker-compose uploads volume + SMTP env passthrough;
.env.example SMTP section.

43 server tests passing (attachment/webhook/notification/savedView
services covered; bulkAction covered in ticketService).
