feat(forms): migrate remaining native date inputs to <DatePicker> / <DateTimePicker>

Sweeps the last ~17 native `<Input type="date"|"datetime-local">`
call sites onto the shared `<DatePicker>` / `<DateTimePicker>`
primitives so date entry is uniform across the app (calendar popover
on desktop, native OS picker on mobile via the primitive's
viewport-aware fallback).

Three patterns handled:

  1. Controlled value/onChange — direct swap to <DatePicker
     value/onChange>:
       audit-log-list.tsx (audit-from / audit-to filters)
       reports/generate-report-form.tsx (date range)
       scan/scan-shell.tsx (expense date)
       reservations/reservation-detail.tsx (end-reservation dialog)
       shared/filter-bar.tsx ('date' filter variant)

  2. RHF `register('field')` pattern — wrapped in <Controller> with
     field.value/field.onChange bridge. The picker's '' → undefined
     normalisation kicks in via `field.onChange(v || undefined)`:
       berths/berth-form.tsx (tenureStartDate + tenureEndDate)
       reservations/berth-reserve-dialog.tsx (startDate)
       companies/add-membership-dialog.tsx (startDate)
       yachts/yacht-transfer-dialog.tsx (effectiveDate)
       invoices/invoice-detail.tsx (paymentDate)

  3. RHF + Date-typed schema — same Controller wrap, plus a
     Date<->YYYY-MM-DD bridge in the render() since the zod schema
     coerces these to Date:
       expenses/expense-form-dialog.tsx (expenseDate)
       companies/company-form.tsx (incorporationDate)

  4. Datetime variants — swapped onto <DateTimePicker>:
       interests/interest-contact-log-tab.tsx (occurredAt + followUpAt)

Skipped because they ARE picker primitives or internal date variants:
  - ui/date-picker.tsx, ui/date-time-picker.tsx (the primitives)
  - shared/inline-editable-field.tsx (the InlineEditableField date variant)
  - dashboard/date-range-picker.tsx (its own popover with min/max gating
    that doesn't map cleanly onto the shared primitive)

Removed now-unused Input imports from four files.

Verified: tsc clean, vitest 1448/1448.
