Add supply (lend) action to individual market pages

[illlefr4u]

Problem

Individual market pages (e.g. morpho.cp0x.com/borrow/market/0x64d6...) currently only expose four actions:

• Add — deposit collateral
• Borrow — borrow the loan asset
• Repay — repay borrowed amount
• Withdraw — withdraw collateral

Supply (lend) is missing — users cannot supply the loan asset directly into a specific market through our interface.

Context

• monarchlend.xyz built an entire app around this feature — direct supply into any market without manually entering market parameters
• supply() is called on the same Morpho contract as the other functions, but the official Morpho UI abstracts lending behind curator vaults
• A permissionless interface should provide direct access to all contract functions without restrictions — that's the core value proposition

Expected behavior

Add a Supply button to individual market pages, allowing users to lend the loan asset directly into that specific market (bypassing curator vaults).
