Unify the app's "choose one" surfaces on the full-screen picker style
(floret-kit FullScreenPicker/OptionPicker) instead of the OptionCard modal
dialogs, for consistency across the app:
- Event editor: visibility + add-field -> OptionPicker; reminder, recurrence
rule, and colour -> FullScreenPicker, with the custom-value Add / OK and the
colour Reset carried in the app-bar via the picker's new `actions` slot; the
save-conflict chooser -> full-screen.
- The recurring scope choosers stay compact OptionCard popups — saving an edit
to, or deleting, a recurring event — since a quick 2-3 option decision reads
better as a popup than a near-empty full screen.
Bumps the floret-kit pin (55ad536 -> e1919ca) for the FullScreenPicker
`actions` passthrough.
