feat: [IOCOM-2969] SEND AAR TTL error screens

[forrest57]

Short description

--- 🔴 DEPENDS ON #7880 🔴 ---

this PR introduces the logic required to display the correct error screens in case of a TTL error in both the mandate creation and mandate validation steps of the AAR delegation flow

mandate validation	mandate creation

List of changes proposed in this pull request

• added required components
• added required i18n entries
• refactored the error handling logic to accomodate for the new components
• tests

How to test

• automated tests should pass.
• make sure the pre-implemented error screens in the AAR flow behave and display as expected

Also, using either the dev-server or proxy software (e.g. proxyman):

• a 500 error in the mandate creation response with {code:PN_MANDATE_ALREADYEXISTS} as the first entry in the errors array should result in its specific error screen. no other configuration (e.g. different http code, different error as the first entry) should result in the same screen.
• a 500 error in the mandate validation response with {code: PN_MANDATE_NOTFOUND} as its first entry in the errors array should behave the same way as the mandate creation response logic.

Pull request overview

Adds support for rendering dedicated UI error screens for specific SEND AAR delegation failures (TTL/mandate-related) during mandate validation and mandate creation, by extending the AAR problem-json error mapping and introducing new error components with related tests/i18n.

Changes:

• Extended getAarErrorBehaviour mapping to support new status+errorCode combinations and added two new error components.
• Added/updated component tests and snapshots to cover the new screens.
• Added Italian i18n strings for the new error screens.
