feat/db: cleanup old account state data db entries

[drahnr]

Important

Targeting main

We recently started tracking historical account state storage ( #1227 ) but that punted on the cleanup, causing unbounded growth of the DB.

The PR adds a cleanup routine to apply_block.

Pro:

• simple, all writing DB transactions happen in one place
• no risk of sqlite locked errors popping up

Con:

• prolonged time the mutex is being held
• does not exploit all possible parallelism of apply_block

Pull request overview

This PR implements database cleanup functionality for historical account state data to prevent unbounded database growth. The implementation adds a cleanup routine that runs during apply_block to delete old vault asset and storage map entries while preserving the latest state and recent history.

Changes:

• Added cleanup_all_accounts function that deletes historical entries older than 50 blocks (excluding is_latest=true entries)
• Created database migration to add partial indices on account_vault_assets and account_storage_map_values tables for efficient cleanup queries
• Integrated cleanup into the apply_block transaction in the store component

After self review, this still has some implications to be addressed, particularly around storage map root calculation of account updates using ad-hoc smt forests.

This makes it harder to review, but if we want further changes to apply_block - which we do, we should keep the sync on the extra file with next to avoid more pain when merging.
