Include KAS and ZK fields from shared receipt into embedded proof

[kojibai]

Motivation

• Shared receipts loaded via the ?r receipt parameter were not exposing author signature and ZK metadata to the embedded proof state, preventing KAS/G16 seals from being displayed/verified.
• The goal is to preserve the full seal data from a shared receipt so subsequent verification UI and logic (KAS/Groth16) can operate on that data.

Description

• When a sharedReceipt is used to populate proof state, the code now copies authorSig into the constructed embeddedProof object in src/pages/VerifyPage.tsx.
• The change also preserves ZK-related fields zkProof, proofHints, and zkPublicInputs from the sharedReceipt into embeddedProof so sealZK logic can run.
• Other existing fields (proofCapsule, svgHash, capsuleHash, bundleHash, shareUrl, verifierUrl) continue to be set as before.

Testing

• No automated tests were run as part of this change.
• Manual inspection and static code checks were used to confirm the added fields are assigned in buildProof when sharedReceipt is present.
