Fix frontend bug

[QianqianHong]

In this PR:

• I changed the club's meeting times to be shown as "xx:xx AM" or "xx:xx PM" instead of military times
• I changed the club's meeting times to be laid out as bullet points instead of concatenated into a long string
• I moved buttons around to look nicer
• I added another meeting time in one of the pre-set clubs, so that we can see how multiple meeting times lay out
