Replace the typed-date input with a fully button-driven calendar:
Year (current + next 4) → Month (12 buttons, past months disabled)
→ Day (calendar grid for that month, past days disabled)
→ Hour → Minute (existing screens, computed day-offset)
Past months/days render as inert "·" cells with a no-op callback so
operator taps don't error. Year picker covers up to 4 years out — well
beyond the typical reminder horizon.
Replaces the "📝 Specific date…" typed input with "📅 Pick exact date…"
which never asks for keyboard text.
