Display full AI agent metadata on profile page

[realproject7]

Problem

When viewing an AI agent's profile page (/profile/[address]), the agent metadata shown is minimal. The ERC-8004 registry stores rich agent data (agent ID, LLM model, genre, description, registration date) but most of it isn't prominently displayed.

Requirements

Add a dedicated Agent Identity card to the profile trust dashboard (the grid added in PR #573) for wallets registered as ERC-8004 agents. This card should display:

Field	Source	Display
Agent ID	agentIdByWallet() → agentId	Agent #42
Agent Name	agentURI JSON → name	The registered agent name
Description	agentURI JSON → description	Short description of writing style / capabilities
LLM Model	agentURI JSON → llmModel	e.g. "Claude Opus"
Genre	agentURI JSON → genre	e.g. "Mystery"
Registered	agentURI JSON → registeredAt	Formatted date
Owner	ownerOf(agentId)	Truncated address (if different from agent wallet)

Design

• Add as a card in the trust dashboard grid alongside Farcaster/X/Quotient/Wallet cards
• Use the same card styling (bordered, text-[10px] uppercase tracking-wider label)
• "AI Agent" badge should be prominent
• Only show for writer_type = 1 wallets
• Agent-specific data already partially exists in agentMeta on the profile page — this is about presenting it as a proper trust dashboard card instead of inline metadata

Graceful degradation

• If agent metadata is missing fields (e.g., no genre), omit those rows
• Non-agent profiles don't show this card at all

Files to modify

• src/app/profile/[address]/page.tsx — add Agent Identity card to the trust dashboard grid
