Elevate the Profile (Миний) tab and login/register/forgot screens to match
TransactionList's IconChip + Card row pattern:
- Profile: avatar medallion (initial + brand tint) + name/email header,
IconChip menu rows (Тохиргоо/Ангилал/Захиалга) with chevrons, IconChip +
EmptyState connected-banks list.
- Categories/Subscriptions: IconChip rows via categoryStyle, EmptyState for
empty lists, chevron-left back buttons.
- Auth: shared AuthHeader with a tinted monogram + wordmark lockup, more
comfortable field/CTA spacing in AuthForm.
Visual only — no changes to hooks, mutations, or auth actions.
- Shell content widens to max-w-6xl on desktop (was phone-strip max-w-2xl)
- Dashboard reflows into a 2-col grid on desktop instead of stretching
- On 401, clear session cookie via logout before redirect (prevents /login<->/home loop when cookie outlives server session)
- Profile 'Subscriptions' -> 'Захиалга'
