Subject: [PATCH] fix: guard InterfaceOptions globals, SetHighlightTexture,
 dynamic class list

CoA-Beta client compat:

  - L15198 InterfaceOptions_AddCategory is nil on the CoA reworked
    FrameXML; guard with 'if InterfaceOptions_AddCategory then ... end'
    so the Plus options panel registration is skipped silently rather
    than aborting addon init.

  - L16477-16478 InterfaceOptionsFrame:HookScript and
    VideoOptionsFrame:HookScript are nil on the CoA client; guard each
    individually so PLAYER_LOGIN doesn't crash.

  - L17186 SetHighlightTexture(0) passes the integer 0 (FDID style)
    which silently no-ops on 3.3.5. Use "" so the highlight is
    actually cleared on locked Plus option buttons.

  - L20066 hardcoded 9-class list excluded DEATHKNIGHT and all CoA
    custom classes from LeaPlusDB.Cooldowns. Build the list dynamically
    via GetNumClasses + GetClassInfo so every playable class on the
    realm gets a cooldown table.
