update v3 schema

[0xroll]

making some changes to the v3 schema.

details regarding the changes made :

1. for token0_amount and token1_amount , does it make sense to get the raw amount for event level data here. there might be instances where new tokens are not added to Dune yet, so not possible to get normalized amount.

2. removed from_address and to_address : these are for transfer events , which belongs to the v3 transfer table.

3. added nft_token_id : this is required to track nft position

4. changed tick_spacing to current_tick (tick of the LP pool at the specific event) . not sure if tick_spacing` is required, will check with christian .

open questions :

1. to standardize the naming convention for event_type [ lowercased / uppercased]

there will be more changes for v3 transfers , waiting for christian to work on the new data and update.
