Publish the admin panel URL and record one testnet transaction per privileged operation #370

Priority

High — required for Tranche 2

User story / Problem statement

The Tranche 2 "Admin panel" measure asks for the admin panel URL and one testnet transaction per privileged operation, signed by a multisig. The console covers the authorities' operations, and the README records neither its URL nor any of those transactions on testnet.

Expected outcome

A README section gives the admin panel's URL and lists one testnet transaction per privileged operation, each signed by the authority that holds it, with the signers and threshold stated.

Acceptance criteria

• The README gives the admin panel's public URL, the one the contract IDs in "Deployed addresses" are read from
• One transaction per operation, grouped by authority: governance (a timelocked change proposed and applied, unpause, a wind-down proposal), guardian (pause the vault, pause the share token, pause the NAV), attester (attest), treasury (deploy_to_custodian), manager (close_epoch) and compliance (allow, a freeze, legal_transfer co-signed by governance)
• Each was made through the admin console, not by script
• Each states the account that signed, its signers and its threshold
• All ran against the contract IDs currently listed in the README

Technical notes

• The list follows the entrypoint matrix in the kit spec; drop any operation the console does not offer and say so.
• Which accounts hold each authority on the testnet deployment is the first thing to settle.
