vAMM implementation introduced a number of approximations to the the formulae, we need to review those and update the spec to match.

Also add a note of the market parameter used for this vegaprotocol/vega#11642

We need a method / API to

1. calculate the minimum valid commitment from:

• market id (for market parameters like tick size and decimals etc.)
• base price
• range
• leverage at bounds

2. calculate minimum range from:

• market id (for market parameters like tick size and decimals etc.)
• commitment amount
• base price
• leverage at bounds

3. calculate leverage at bounds:

• market id (for market parameters like tick size and decimals etc.)
• commitment amount
• range
• base price

We should make clear that a commitment amount that's been valid stays valid (unless the price move outside the range).

Comment from @JonRay15: "ideally this would be baked into that same estimateAMMBounds API I would imagine"
