feat(l1): improve healing

[fmoletta]

Motivation
Reverts the "slow but safe" approach to healing taken by #1763 and instead adds the intermediate nodes received from peers to the trie.

Description

• Write nodes fetched during healing to the state instead of writing only leaf values
• Track paths left in queue when a healing cycle ends due to pivot staleness
• Condense snap checkpoint clearing to one single method
• (Misc) Move some noisy p2p info tracing to debug
• (Fix) When executing full blocks after the pivot block during snap sync execute the block first before setting it as canonical

Comments
A not so pretty solution was implemented on the storage_healer (the startup flag) to avoid blocking storage healing at the start. This can and will be improved but doing so in this PR is not worth it when follow up PRs will already touch up on this logic when parallelizing storage node fetching (similar to storage ranges)

Testing
This proved to work fine in Mekong testnet when introducing forced sleeps and delays to force healing. But it is still too slow to work on Holesky testnet, this should improve once we add more parallelization to state sync & healing

Closes #issue_number
