[GIP-69] Reduce min debt size for Credit Managers

Motivation:

Another side effect related to CRV price drop is connected with ca owners, which now has very strict limits like degenNFT & minimal debt (150K USDC atm). As long term consequences, it could reduce Credit Account (later - CA) usage.

Suggestion:

To democratise process of CA opening, the protocol could change these parameters:

1. reduce maxEnableTokens to 3 (from 8), which limits potential liquidation costs maxEnableTokens here is amount of token that are considered as collaterals in Credit Account. The higher value - higher potential liquidation costs.

2. reduce minDebt to Credit Managers:

• 25 eth for WETH CM (same for WETH CM for Curve v2 tokens),
• 50k DAI for DAI CM,
• 50k USDC for USDC CM,
• 1.65 WBTC for WBTC CM,
