For the PIN pages:
- add a `pinSettingInProgress` bool hint to `KeycardCreatePinPage` when
setting/authorizing the PIN is in progress to be able to correctly
display the Back button
- don't display the "success" image yet when in progress
- use the hint in related flows
- extract the default attempts numbers to `Constants`
For the backup seed phrase sequence:
- the mnemonic is a string and gets submitted when exiting the
BackupSeedphraseReveal, not right after its (re)creation
- when starting the flow (going from `KeycardCreatePinDelayedPage`),
replace instead of push, so that Back skips the PIN page
- fixup the related SB pages
Fixes#17218
- integrate the PUK unblock flow into the Onboarding and Login screen
- added a dedicated SB page for it
- remove the `Locked` keycard state everywhere in favor of `BlockedPIN`
and `BlockedPUK`
- fix the various "Locked" buttons, based on the context and the state
of the keycard
Fixes: #17092
