feat(templates): a field's defaultValue seeds a new line in the item dialog

[delchev]

What

defaultValue: on a field already reached the model — it becomes the column's DB DEFAULT and suppresses a required field's presence check — but no UI ever seeded from it. A document's item dialog built a new line out of blanks (false for a checkbox, null for a number, '' otherwise), so every authored default was invisible until the row was posted.

The visible cost is Fill Month. The guide promises it "creates an 8-hour line for every working day (Mon–Fri)", and the dialog's skip-existing-days and Mon–Fri rules do match — but Hours opened empty and Billable opened off, so the one-click promise was really type-8-toggle-billable-click.

Change

The detail registry emits the authored default as def on the column, in the shape the draft holds:

column	emitted
NUMBER	def: 8 (real number)
CHECKBOX	def: true (real boolean)
DROPDOWN (numeric FK)	def: '2' (string — the draft keeps FKs stringified so they match an option's data-value)
no default declared	no key at all

openRowDialog seeds a new line from it. An existing row is untouched — re-defaulting a value the user deliberately cleared would silently undo it.

Scope

Deliberately item-dialog only. The main create form is left alone: every entity with an init: status carries a dataDefaultValue too, so seeding forms as well would visibly change create screens across the whole fleet — a separate change with its own blast radius, not something to smuggle in behind a dialog fix.

The DSL key itself needed no work — it already binds and already emits. It was, however, undocumented beyond a passing mention, so intent-assistant-guide.md now describes all three things it does.

Verification

Both templates rendered through a real Velocity engine with a NUMBER / CHECKBOX / numeric-DROPDOWN / no-default / text-default property set, confirming the table above and that the rendered registry parses as JS (node --check).

The seeding line was then simulated over new / edit / cleared rows:

• new line takes the defaults → {Hours: 8, Billable: true, Status: '2', Note: ''}
• edited row keeps its stored values
• a cleared value is not re-defaulted
