time_edit_field now cycles through 5 fields (hour/min/day/month/year) via long-press CONFIRM. Up/down adjusts whichever field is focused, with day clamped to Days_In_Month() when month/year changes, and Clock_RecalcWeekday() called after every date edit so the weekday label stays in sync. UI_UpdateSetTimeDigit() now also refreshes the weekday abbreviation when editing day/month/year, since the computed weekday can change independently of which digit was actually touched. Save writes the full date+weekday via PCF8563_WriteDateTime(). Also removes PCF8563_ReadTime()/WriteTime(), now unused since every caller was updated to the DateTime variants directly.
