feat: History log in content library components and containers [FC-0123] (#2948)

- Implements the API functions and hooks to fetch:
    - Draft history entries for components and containers.
    - Published history groups for components and containers.
    - Published entries within a history group.
    - Creation entry for components and containers.
- Implements:
    - `HistoryCreatedLogGroup`: Group for the create event.
    - `HistoryDraftLogGroup`: Group and entries for draft changes (collapsible).
    - `HistoryPublishLogGroup`: Group and entries for published changes (lazy-loaded on expand).
    - `HistoryComponentLog`: Renders the full history for a library component.
    - `HistoryContainerLog`: Renders the full history for a library container (unit/section/subsection).
    - `ContainerDetails`: New "Details" tab in the container sidebar that shows the container history log.
