fix(IT Wallet): [SIW-1795] Problem with SPID Login Using Custom Tab

[RiccardoMolinari95]

Warning

Depends on #6455

Short description

This PR addresses the issue encountered by some users when logging in via SPID for PID issuance on ITWallet, specifically related to the opening of the CustomTab.
Unified the authorization flows for SPID, Cie + PIN, and CieID. Previously, SPID and CieID had a unique flow, while Cie + PIN followed two separate flows (startAuthFlow and completeAuthFlow). Replaced the opening of a CustomTab with a WebView for SPID authentication.

List of changes proposed in this pull request

• Created a new screen ItwSpidIdpLoginScreen to handle the SPID authentication process within a WebView. This screen loads the authUrl generated by startAuthFlow and sends the authRedirectURL back to the state machine when it contains itWalletIssuanceRedirectUri
• Refactored the XState machine states related to eID issuance for CieID and SPID, aligning them with the existing flow for CIE + PIN
• Added openUrlAndListenForAuthRedirect, which opens the authUrl in the browser for CieID and provides the authRedirectURL
• Created a new actor getAuthRedirectUrl used in the CieIDBuildAuthRedirectUrl state of CieID, which utilizes openUrlAndListenForAuthRedirect to complete the authentication

How to test

To test the changes, try obtaining the eID using all three authentication methods (SPID, Cie + PIN, and CieID) and ensure that the eID is successfully obtained in each case. After successfully obtaining the eID, proceed to obtain a credential and ensure that the process completes without issues.
