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. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
