refactor(ui): draw InlineTextField/OptionCard/DialogControls from floret-kit components

Adopt the floret-kit components module for the three widgets whose kit form is
identical to Calendula's, deleting the app-local copies and repointing imports.

One behavioural guard: the kit's InlineTextField defaults capitalization to
Sentences (the family default), where Calendula's defaulted to None. The three
Calendula call sites that relied on the old default now pass
KeyboardCapitalization.None explicitly — notably the guest **email** field,
which must not auto-capitalize — so behaviour is unchanged.

The richer app-local primitives (GroupedRow with dimmed/container,
CollapsingScaffold with actions/snackbar/predictive-back) stay local for now:
they're supersets of the kit's versions, so consuming the kit forms would drop
features. Promoting those into the kit is a follow-up.

Compile + unit tests + lintDebug green.
