feat(eoi-generate): Include-yacht toggle to omit Section 3 when yacht is a placeholder

EoiGenerateDialog gains an inline "Include on EOI" checkbox in the
Section 3 header (renders only when ctx.yacht is set; defaults ON so
existing behaviour is unchanged). When OFF, the generate-and-sign POST
flips includeYachtDetails=false on the body; service blanks
eoiContext.yacht before either pathway runs:

- Documenso template payload: buildDocumensoPayload reads no yacht so
  yacht.* and owner.* merge fields ship empty. Existing template tolerates
  blanks per the "left blank if absent" copy.
- In-app PDF fill (pdf-lib): generateEoiPdfFromTemplate sees no yacht so
  AcroForm field writes for the yacht block are skipped.

Persists the rep's choice in the document-create audit log
(metadata.includeYachtDetails) so an audit trail records explicit opt-outs
even though documents has no JSONB metadata column today.

ft/m unit toggle in the Section 3 header now hides when Include is OFF
(unit choice is meaningless without yacht details).
