feat(reminders): dynamically adjust popup width based on content

- Calculate the maximum line width of the reminders output in
  `show_reminders.sh`
- Pass the calculated width and a temporary file to the tmux popup in
  `main.sh`
- Ensure popup width is at least 40 and does not exceed the tmux window
  width
- Improve display by preventing horizontal scrolling and better fitting
  content
