* fix(crypto): use authenticated encryption for IDP intent tokens
IDP intent tokens were encrypted with AES-CFB which provides no
integrity protection, making them malleable. Switch to A256GCM via
the existing AuthAlgorithm interface (EncryptToken/DecryptToken),
the same approach already used for OIDC and session tokens.
The idpConfigEncryption key type is widened from EncryptionAlgorithm
to AuthEncryptionAlgorithm so that data-at-rest encryption (IDP
client secrets, LDAP bind passwords, SAML keys) continues to use
the CFB path unmodified.

* fix(proto): raise IDP intent token max length to 500 for authenticated tokens
The switch to authenticated A256GCM (JWE compact serialization) makes IDP
intent tokens longer (~270 chars) than the previous AES-CFB base64 output.
Raise the max_len/max_length validation and OpenAPI constraints on every
idp_intent_token field from 200 to 500 so the new tokens are accepted:
user v2/v2beta (idp + user_service), session v2/v2beta, and resources
user v3alpha.

# Which Problems Are Solved
As part of #11035 , this PR implements the IDP intent check logic for
session validation
# How the Problems Are Solved
- Inject encryption algorithm for IDP intent tokens at DB initialization
- Add the IDP intent repository as an invoke option
- Rework crypto mocks using gomock
- Implement IDP intent check logic
- minor - DB: expand IDP Intent deletion testing table with a test case
where IDP intent is not found
# Noteworthy
I did not implement `domain.Transactional` given the doubts that
@adlerhurst expressed in https://github.com/zitadel/zitadel/pull/11804 .
So, there is no transaction AT ALL in here because the `Execute()`
method contains one single DB call (Delete) and `Validate()` just does
Get calls.
# Additional Context
