fix(2fa-recovery-code-error): [Auth/PM-19885] Better error handling when 2FA recovery code is invalid (#16145)

Implements better error handling when a user enters an invalid 2FA recovery code. Upon entering an invalid code:
- Keep the user on the `/recover-2fa` page (This also makes it so the incorrect code remains in the form field so the user can see what they entered, if they mistyped the code, etc.)
- Show an inline error: "Invalid recovery code"
