chore(IT-Wallet): [SIW-3849] Add source to avoid sending mixpanel method tracking on notfound bottomsheet

[DavideOnano]

Short description

Fix IT-Wallet analytics in the CIE+PIN KO path: when users declare they don’t have the PIN and choose an alternative method, ITW_ID_METHOD_SELECTED is no longer tracked.

List of changes proposed in this pull request

• Added optional source to select-identification-mode event.
• Set source: l3-missing-pin-ko in the “Non ho il PIN” CIE bottom-sheet flow.
• Skipped ITW_ID_METHOD_SELECTED tracking when source is l3-missing-pin-ko.
• Added eid action tests.

How to test

In L3 activation, go through CIE+PIN -> "Non ho il pin" -> choose another method.
Verify ITW_KO_STATE_ACTION_SELECTED is tracked and ITW_ID_METHOD_SELECTED is not.
