feat(reports): parameterized renewal-notice report + legacy report reference

Replaces ~40 legacy Access renewal-notice report clones (one per carrier
per coverage tier, e.g. AMPL/RC/LIC RENEW X MES/VENCE ATLAS 13/2013) with
one parameterized aviso-renovacion report driven by real Policy/Vehicle/
coveragesJson data instead of hand-typed label text per clone.

- schema.prisma: add RenewalNotice, replacing the legacy CONTROL <ramo>
  RENEW[2/3] X MES paper log of which notice generation was sent
- reports: new "letter" ReportFormat + aviso-renovacion registry entry +
  LetterLayout renderer in ReportRunner.tsx
- docs/RENEWAL_NOTICES.md + migration/legacy_report_defs/: extracted (via
  Application.SaveAsText, since the VBA project wouldn't load) and
  documented the legacy report/query chain this replaces

Coveragesjson key names and a mark-as-sent mutation are still unverified/
unbuilt — see caveats in docs/RENEWAL_NOTICES.md.
