feat(10-02): type-branched field rendering in preparePdf()

- Add getFieldType import from @/lib/db/schema
- Replace single-variant blue loop with branched rendering per field type
- client-signature: unchanged blue rectangle + "Sign Here"
- initials: purple rectangle + "Initials" label
- checkbox: gray rectangle + X diagonal lines (embedded at prepare time)
- date: amber rectangle + "Date" label (actual date stamped at POST time)
- text: light gray rectangle, no label (visual marker only)
- agent-signature: skipped (no placeholder drawn)
