fix: issuer name showing as uuid

[KjartanE]

Signed-off-by: Kjartan Einarsson kjartanreinarsson@gmail.com

Summary of Changes

Fixes the issuer name appearing as a raw connection UUID on the Credential Offer and Credential Details screens when the underlying connection has no alias or theirLabel.

• useCredentialConnectionLabel now accepts an optional overlay argument and, when the connection has no alias/theirLabel, falls back to overlay.metaOverlay.issuer before falling back to 'Unknown Contact'. The raw connectionId UUID is no longer returned as a label.
• CredentialOffer and CredentialDetails screens updated to pass the resolved overlay into the hook so the issuer name from branding metadata is used.

Testing Instructions

1. Receive a credential offer from an issuer where the underlying connection has no alias / theirLabel set, but a branding/meta overlay with an issuer value is available.
2. Open the Credential Offer screen — the issuer name from the overlay should be displayed (not a UUID).
3. Accept the credential and open the Credential Details screen — the issuer name should also be displayed there.
4. Regression check: for credentials whose connection does have an alias or theirLabel, that value should still be shown unchanged.
5. Regression check: for credentials with no connection at all, the label should still fall back to Unknown Contact.

Acceptance Criteria

• Credential Offer and Credential Details screens never display a raw connection UUID as the issuer/contact label.
• When connection alias / theirLabel exist, they continue to take precedence over the overlay issuer.
• When neither alias/theirLabel nor an overlay issuer is available, the label falls back to Unknown Contact (no connection) or empty string.

N/A — useCredentialConnectionLabel's new overlay parameter is optional, so existing callers continue to work without changes.
