Display human-readable names for known payer wallets

[timfong888]

Outcome

When a user visits the Filecoin Pay Dashboard, wallet addresses that match entries in wallet-map.md display their human-readable names instead of truncated addresses.

Acceptance Criteria

• Dashboard Top Payers shows "Storacha", "Tippy", "PinMe" for matched addresses
• Payer Accounts page shows wallet names for matched addresses
• Addresses not in mapping show truncated format (0x1234...5678)
• Wallet mappings stored in wallet-map.md (human-editable)

@timfong888 do you plan to maintain this in the long term and open for public submission?

Also we need a design from UXIT for front end before this can pass over to eng.

Can we do the design now, but make the implementation M4.5?

I discussed it with the Stakeholders: the framing was that given that we can accept or decline the PR, it will be maintained.

Here is my implementation, but I agree, let's push it out and see if we can keep it out to M4.5
