Missing dapp_pool_fee Network Property

[kmlbgn]

Description

Current logic uses dapp.PoolFee to fetch fee for dp/denom swap and redemption, but this value is never set, even at pool creation.
Additionally, a TODO related to the fee application has not been addressed:

sekai/x/layer2/keeper/lp_swap_redeem_convert.go

Lines 18 to 30 in 1b8573d

	func (k Keeper) OnCollectFee(ctx sdk.Context, fee sdk.Coins) error {
	// TODO: The fixed fee will be applied after the swap from where
	// - `50%` of the corresponding tokens must be **burned** (deminted)
	// - `25%` given as a reward to liquidity providers
	// - `25%` will be split between **ACTIVE** dApp executors, and verifiers (fisherman).
	// Additionally, the premint and postmint tokens can be used to incentivize operators before
	// dApp starts to generate revenue.
	err := k.bk.BurnCoins(ctx, types.ModuleName, fee)
	if err != nil {
	return err
	}
	return nil
	}

Expected Behaviour

dApps pool fee cannot be set by owners and should be set network-wide through a network property called dapp_pool_fee when the dApp proposal is approved.
The TODO should be addressed.
