* [MM-64634] Improve license error for wrong service environment

When a cryptographically valid license is uploaded to a server running a
different service environment (e.g. a production license on a test/dev
server, or vice versa), ValidateLicense now retries verification against
the alternate environment's public key. On success it returns a distinct
error that callers surface as the new WrongEnvironmentLicenseError, giving
admins an actionable message instead of the generic "Invalid license file."

Genuinely corrupt licenses still return the existing InvalidLicenseError.

* [MM-64634] Add tests for wrong-environment license error mapping

Cover SaveLicense (the System Console upload entry point) returning
WrongEnvironmentLicenseError for a license signed for another service
environment, and add a direct unit test for NewLicenseValidationAppError.

* Add audit logging for wrong-environment license upload failures

Handle WrongEnvironmentLicenseError in addLicense and localAddLicense
so environment mismatches are logged distinctly instead of falling
through to the generic unable-to-save message.

* Log wrong-environment audit in LicenseFromBytes error path

addLicense validates the license before SaveLicense, so
WrongEnvironmentLicenseError is returned from LicenseFromBytes and
never reaches the SaveLicense audit handler.

* Address PR feedback: remove license validation audit logging from addLicense

Per review feedback, the per-error-id audit logging added to the
LicenseFromBytes failure path in addLicense doesn't belong in the audit
logs. Remove it to clean up the diff; the AppError is still returned to
the caller unchanged.

* Remove wrong-environment license audit logging

Per review feedback, the wrong-environment license classification does not
belong in the audit logs. Revert the audit logging additions in both the
cloud and local license upload handlers.

* Split wrong-environment license error by direction

Per review feedback, distinguish between a production license uploaded to a
test/dev server and a test/dev license uploaded to a production server. Each
case now maps to its own AppError ID and user-facing message instead of a
single generic wrong-environment error.

* Restrict wrong-environment license fallback to signature failures

Only treat alternate-key verification success as a wrong-environment
mismatch when the primary key failed with rsa.ErrVerification. Other
primary-key failures (e.g. malformed key material) are now surfaced
unchanged instead of being masked as a wrong-environment license, and
non-verification errors from the alternate-key check are no longer
discarded.

* Regenerate store layers and mocks for SessionStore
