Clarify Prompt Jam proof fields: MEMWAL_AGENT_ID, account object, blob count, and explorer links

[Derojuu]

While building a Walrus Session 5 Prompt Jam submission, the proof requirements
were hard to map to the MemWal UI/MCP flow.

The form asks for MEMWAL_AGENT_ID and an explorer link showing the MemWal account
object/memories, but first-time users may not know whether MEMWAL_AGENT_ID means:

• the dashboard delegate key public key
• the MemWal account ID
• a Sui object ID
• a wallet address
• a blob ID from a memory write

It was also unclear how to confidently prove blob count from the MCP workflow. The
MCP tools return blob IDs after writes, but a beginner still has to infer which ID/
count/link belongs in the final form.

Suggested improvement:
Add a Prompt Jam proof section to the MemWal docs or dashboard that shows:

1. the exact MEMWAL_AGENT_ID value to submit
2. the exact explorer/account-object link to submit
3. total memory blob count for the active agent/account
4. recent blob IDs with Walruscan links
5. a copy button for all submission proof fields

This would make the prompt-jam proof flow much easier for non-expert users.
