Adds a new event `NeuronRegistrationBurn` that is emitted during burned registration to track the exact amount of alpha that was burned. The event includes: - netuid: The subnet where registration occurred - hotkey: The registered hotkey - tao_cost: The TAO amount that was spent - alpha_burned: The alpha amount that was actually burned This enables accurate tracking of registration burn amounts for accounting and analytics purposes. Fixes opentensor#2104

Summary
Adds a new event
NeuronRegistrationBurnthat is emitted during burned registration to enable accurate tracking of the alpha amount that was burned.Problem
Currently, it's impossible to calculate how much alpha was burned by neuron registration (as noted in #2104). This makes accurate balance bookkeeping and analytics difficult.
Solution
Added a new event
NeuronRegistrationBurn(NetUid, T::AccountId, TaoCurrency, AlphaCurrency)that includes:netuid: The subnet where registration occurredhotkey: The registered hotkeytao_cost: The TAO amount that was spentalpha_burned: The alpha amount that was actually burnedThe event is emitted alongside the existing
