(#47) Fix alarm list text wrapping and recurrence summary

[bfalls]

Fixes #47

• Reworked alarm row layout to use a weighted column and spacer so label text wraps to multiple lines while the enable switch stays aligned on the right.
• Added recurrence summary generation with special cases (every day/weekday/weekend) and formatted day lists, and appended the summary to the alarm label when present.
• Capped the alarm label TextField in the editor to three lines to prevent the bottom controls from scrolling off-screen.
