Favorite & hidden accounts

[Hannsek]

Prerequisite: #6781

Feature that introduces the ability for users to mark/label their accounts as either favorite or hidden.

Information whether the account is favorited or hidden would be stored in the same file as labels are. (Connected with https://github.com/trezor/trezor-suite/issues/6304)

Other changes:

• New Favorite and Hidden tab in left (accounts) column (present only if at least one account is marked like this)
• Under the Details (Account) tab, create separate Organize account field
• 2 new icons that would appear next to the account name

Design:
