The earlier 'Currently on file' indicator hung off readonlyValue, which
is sourced from evalState (only carries current_stage). For file fields
the prefill lives in RHF state, not in evalState, so the indicator
never fired.
Replaced with a FilePriorIndicator subcomponent that subscribes to the
field's RHF value via useWatch and renders a small leaf-50 banner with
a paperclip glyph when a previous attachment is present. Falls silent
the moment the user picks a new file (RHF value becomes a FileList).
Filename is derived from whatever shape Civi returned — bare string,
object with file_name/name/label/filename, or numeric file id (generic
message in that case).
- H3: Live currency preview below currency inputs shows the value formatted
with thousands separators (en-US, USD) using Intl.NumberFormat. Skipped
inside matrix cells to keep the Y1 monthly table compact.
- M1: Date inputs now apply min/max bounds. Default window is 1900-01-01 to
2100-12-31; per-field override via FieldConfig.min/max as ISO strings.
- H6: On successful submit, replace the form with a SuccessDestination card
(large checkmark, org name, "Submit another" + "safe to close" affordance).
Prevents accidental duplicate submits from back-button / autofill replay.
- M6: Sticky submit bar respects iOS safe-area-inset-bottom.
FieldRenderer now takes a control prop so the currency preview can subscribe
to its single field via useWatch without re-rendering the whole form.
