Update DeFi Positions docs to indicate coming soon status

The DeFi Positions endpoint is temporarily unavailable while being
rearchitected for expanded protocol coverage. Updated documentation
to reflect this status:

- Added prominent warning banner on main docs page
- Updated OpenAPI spec title and descriptions
- Added "Coming Soon" indicator to compute units table
- Changed present tense to future tense in descriptions

+<Warning>
+**Coming Soon: This endpoint is temporarily unavailable**
+
+The DeFi Positions endpoint is currently being rearchitected to provide expanded protocol coverage and enhanced functionality. We're working to bring it back with improved support for more DeFi protocols and chains.
 
-The DeFi Positions API returns a wallet's active positions across liquidity pools, lending protocols, yield strategies, and tokenized DeFi assets.
-Each position includes token holdings, USD valuations, underlying asset metadata, and protocol-specific details such as tick ranges, collateral status, or reward accruals.
+Please check back soon for updates on availability.

+The DeFi Positions API will return a wallet's active positions across liquidity pools, lending protocols, yield strategies, and tokenized DeFi assets.
+Each position will include token holdings, USD valuations, underlying asset metadata, and protocol-specific details such as tick ranges, collateral status, or reward accruals.
 
 <Note>
-This endpoint is currently available at the beta path (`/beta/evm/defi/positions`).
-Schemas are stable, but response fields may expand as we onboard new protocols.
+When available, this endpoint will be accessible at the beta path (`/beta/evm/defi/positions`).
+The information below represents the planned functionality and supported protocols for the rearchitected endpoint.
