feat(freight-api): replace canned reports with a generic report engine

Nuke the 17 hand-written raw-SQL reports (no pagination, hard LIMITs) and
the reports module built around them. Replace with a resolver contract:
a report declares columns/filters/permission and a TypeORM QueryBuilder;
ReportRunnerService applies filtering, a whitelisted sort, offset/limit
paging, and a COUNT(*) FROM (query) wrapper for the total (getCount() is
wrong for GROUP BY). ReportExportService re-runs the same resolver
unpaginated for xlsx (exceljs) and pdf (existing PdfRenderService, now
landscape-capable) exports.

Ships with 4 reports: bookings-list, revenue-by-customer,
aging-receivables, contract-utilization. Catalog + per-report permission
checks live in the controller; adding a report is one new definitions/
file plus a REPORT_KEYS entry, no frontend change.
