If segments exist, show buttons to skip past them - if clicked they send a yt video link with ?t set

[Sv443]

• It starts with one button like: ⏭️ Embed with timestamps
  If clicked within ~60s, the bot should send a reply with the video link, plus a ?t param (starting out at 0), so the embed allows skipping to that time.
• The buttons could look like: 🇦 05:32 🇧 11:08
  They should only show up if there are segments and isAutoReply is false (only on manual command trigger).
  After being clicked by the command user, the message containing the embed link gets edited.
• All buttons should have a customId that starts with a common pattern and also includes the message ID and other needed info, to allow recovery even if the bot restarts.
• The segments should be numbered with emojis or letters like:

  🇦 05:30 - 05:32 Interaction Reminder (like & subscribe)
  🇧 11:08 Highlight (see issue #3)
  

• There could be an extra guild config setting that controls how the buttons show up: "hidden", "always" or "onManualCmd"
