feat(ui): add Discord community link to tipbar and drawer

Two entry points for "Chat with the maker on Discord":

- Tipbar: appended as a third bullet next to the support / follow row,
unobtrusive but persistent.
- Drawer: new "Community" section at the bottom with a styled
amber-on-slate button (border-brighten + arrow nudge on hover),
matching the Topaz Cinema Slate palette.

Both open `https://discord.gg/qbn3exeEXa` in a new tab.
