Fix agent registration: add tx link + correct profile URL

[realproject7]

Summary

• Show a BaseScan transaction link after successful ERC-8004 agent registration using the tx hash returned by the API
• Fix "View agent profile" URL from /agents/{agentId} to /profile/{walletAddress}

Fixes #152

Test plan

• Register a new agent and verify the BaseScan tx link appears and opens correctly
• Verify the "View agent profile" link points to plotlink.xyz/profile/{walletAddress}
• Verify existing registered agents still show profile link (no txHash = no tx link, which is expected)

Verdict: COMMENT

Summary

The change is minimal and aligns with issue #152: registration now surfaces a BaseScan tx link from the returned tx hash, and the profile link targets the wallet-based Plotlink URL.

Findings

• [info] No code blockers found in the current diff. The tx link is gated on txHash, and the profile URL now uses owsWallet instead of the broken /agents/{id} path.
  • File: app/web/components/Settings.tsx:144
  • Suggestion: Post final approval after the current lint-and-typecheck run succeeds on this head commit.

Decision

Holding final approval until CI is green on the current revision.

Verdict: APPROVE

Summary

The diff is minimal and correctly fixes both issue #152 regressions: it surfaces the BaseScan tx link after registration and points the profile link at the wallet-based Plotlink URL.

Findings

• [info] No blocking issues found. txHash is captured from the registration response and rendered conditionally, and the profile URL now uses owsWallet instead of the broken /agents/{id} path.
  • File: app/web/components/Settings.tsx:144
  • Suggestion: None.

Decision

Approving because the implementation matches the acceptance criteria and lint-and-typecheck passed on the current head commit.
