feat(eoi): seed Standard EOI in-app template per port

Adds a new per-port document_templates row of type 'eoi' containing an
HTML EOI / Letter of Intent body with {{section.field}} merge tokens
that mirror the EoiContext shape. Enables the in-app pdfme PDF path as
an alternative to the Documenso template flow.

- New getStandardEoiTemplateHtml() returns the Letter-sized HTML body
  with Applicant / Yacht / Owner / Berth / Interest / Signatures blocks
- STANDARD_EOI_MERGE_FIELDS exported for resolveTemplate wiring (11.4)
- seed-data.ts inserts one document_templates row per port inside the
  existing withTransaction block, between ownership transfers and
  interests, using SEED_USER_ID for audit consistency
