Once a lock date is set on a company, report lines that look back before a given date, such as a Balance Sheet's "Profits (Losses) from Previous Years", could silently lose data. Any line that gets captured in a snapshot and uses a date scope 'to_beginning_of_*' was affected.

Snapshots are computed on the options of the lock date and stored with their 'date' set to the options' date_to (the lock date). Only 'from_beginning' actually evaluates the accounting up to date_to. The 'to_beginning_of_*' scopes stop right before the period or fiscal year, so the data really aggregated stops earlier than the stored date:

  - 'to_beginning_of_fiscalyear': up to a whole fiscal year earlier.
  - 'to_beginning_of_period': up to a whole period earlier.

When the report is rendered, the engine sums only the moves dated after the snapshot's date and adds the snapshot's data. Everything between the snapshot's real cut-off and its (later) stored date is never counted.

Aim the options at the lock date so each scope's bound falls on it, and store the date really covered(using _get_date_bounds_info()). The snapshot's date then always matches its data, and "to_beginning_of_*" covers the last fiscal year starting before the lock date instead of forcing every later render to rescan it.

Snapshots written before this fix still hold the mismatched date, so the account_codes sub-engine version is bumped to 2 to re-trigger the snapshots generation
