rio: remove duplicate Dean's List economic model record

deans-list-enhance-economic-model.md and deans-list-enhancing-economic-model.md
are duplicates of the same proposal (same proposal_url, same dates). Keeping
deans-list-enhancing-economic-model.md which has better analysis and links to
the treasury-buyback-model claim.

Fixes self-review feedback on PR #1753.

-# Dean's List: Enhancing The Dean's List DAO Economic Model
-
-## Summary
-The proposal restructures The Dean's List DAO's payment model to charge clients in USDC, use 80% of revenue to purchase $DEAN tokens, distribute those tokens to DAO citizens as payment, and retain 20% DAO tax in USDC. The model aims to create consistent buy pressure on $DEAN while hedging treasury against token volatility.

-## Market Data
-- **Outcome:** Passed
-- **Proposer:** IslandDAO
-- **Resolution:** 2024-07-22
-- **Proposal Account:** 5c2XSWQ9rVPge2Umoz1yenZcAwRaQS5bC4i4w87B1WUp
-
-## Economic Model
-- **Revenue Structure:** 2500 USDC per dApp review, targeting 6 reviews monthly (15,000 USDC/month)
-- **Tax Split:** 20% to treasury in USDC (3,000 USDC/month), 80% to $DEAN purchases (12,000 USDC/month)
-- **Daily Flow:** 400 USDC daily purchases → ~118,694 $DEAN tokens
-- **Sell Pressure:** Assumes 80% of distributed tokens sold by contributors (94,955 $DEAN daily)
-- **Net Impact:** Modeled 5.33% FDV increase vs 3% TWAP requirement
-
-## Significance
-This proposal demonstrates futarchy pricing a specific operational business model with quantified buy/sell pressure dynamics. The structured approach—USDC revenue → token purchases → contributor distribution → partial sell-off—creates a measurable feedback loop between DAO operations and token price. The 20% USDC tax hedge shows hybrid treasury management within futarchy governance.

-## Full Proposal Text
-
-*Source: futard.io, tabled 2024-07-18*
-
-The proposed model involves continuing to charge clients in USDC and using the collected USDC to purchase $DEAN tokens. These tokens will be distributed to DAO citizens as payment for their work, replacing USDC payments. The DAO tax will remain in USDC to hedge against $DEAN price fluctuations. This creates constant buying pressure on the $DEAN token.
-
-Example: DAO Tax @ 20%, Cost of dApp review 2500 $USDC
-- 500 $USDC goes to the treasury
-- 2000 $USDC used for purchasing $DEAN tokens (560k $DEAN, price goes up)
-- DAO Citizens paid 560k $DEAN; 80% sell to pay bills (448k $DEAN hits market)
-- Price always achieves a higher low on each cycle
-
-### Detailed Analysis
-- Current FDV: $337,074
-- Daily Trading Volume: $500
-- Circulating Supply: 100,000,000 $DEAN
-- Current Price: $0.00337
-
-With 400 USDC daily purchase (80% increase in buy volume), estimated 24% price increase, 15% decrease from sell pressure.
-- Initial FDV: $337,074 → New FDV: $355,028 (5.33% increase)
-- Exceeds TWAP 3% requirement ($347,186)
