feat: free fees for thor holders before tip 014

[NeOMakinG]

Description

This is implementing free fees for thor holders before TIP 014 proposal

I don't have enough funds to do a full swap to test if fees are effectively removed, but assuming setting fees to 0 inside calculateFees effectively change it

I didn't make the votePower slide systemic on purpose as this thing is supposed to stay for a few month and the lift would be a bit more risky, happy to discuss it in a follow up if it bring value

Issue (if applicable)

closes #8019

Risk

Medium, fee calculation could lead user wrongly

High Risk PRs Require 2 approvals

What protocols, transaction types, wallets or contract interactions might be affected by this PR?

Testing

• Check regular trade fees without an account holding THOR, under 1000 and over 1000
• Check trade using 0xC85feF7A1b039A9e080aadf80FF6f1536DADa088 as a spoofed address, to see that trade fees are free because of THOR holding before the proposal
• You could also verify that new Date().getFullYear() <= 2025 is true and new Date().getFullYear() <= 2024 is false to verify if it will be disabled programmatically
• Also verify the mixpanel event is sent on trade (if you have enough funds)

Copy here is unfortunately wrong. Trades under 1k are already free

Should say "Thor holders trade for free through 2024"

Looking very nearly good to go, just a few comments and q's before we get this in!

making a note for posterity that we are currently displaying the thor discount as a fox power discount. easy mode just disable the modal for thor free trades so we don't have to mess with more UI that will only be there for 2 months.

Also noticing what looks like an outstanding bug and potential improvement related to getVotingPower.

Bug: switch wallet does not correctly fetch the new/appropriate voting power for the new wallet. i started with my native wallet and then switched to the frame wallet with test address. after switching the wallet, the discount being applied is still for my native wallet.

Improvement: you can start interacting with the trade widget to get quotes immediately and get a quote with fees displayed before the snapshot logic completes. once the snapshot voting power completes, it triggers a refresh of the trade input component and looks weird. seems like we could add a loading state check to keep the quotes displayed, but the fee breakdown loading until voting power fetch is completed and then show (no refresh of state).
