* studio(ui): use the --primary brand token for the avatar fallback color
The fallback profile avatar hardcoded #14b789, a slightly different green
from the app's general brand color (--primary = #17b88b, used by the send
button and every other primary-colored control). Next to primary-colored UI
-- e.g. the artifact preview/code panel -- the avatar's off-brand shade looked
inconsistent ("changes color weirdly"). Point avatarBgStyle() at
var(--primary) so the avatar always renders the general brand green and
follows the theme token.
Verified live in Studio: the avatar was rgb(20,183,137) (#14b789) while
--primary resolves to rgb(23,184,139) (#17b88b); the fix unifies them. This
is the only hardcoded brand-green left in the frontend -- every other
brand-green element already uses --primary / bg-primary.

* studio(ui): add literal fallback to the avatar --primary token
UserAvatar is a reusable component; if it is ever rendered outside the theme
root (where --primary is undefined), var(--primary) alone would compute to
transparent. Use var(--primary, #17b88b) so the avatar stays branded in that
edge case. When --primary is defined (the normal case, app-wide) it always
wins, so this changes nothing in practice -- verified in a browser:
var(--primary)=rgb(23,184,139), and an undefined var correctly falls back to
the literal.
