Monthly development reports and easier list navigation

Thank you for your feedback and bug reports!

• Improved restoration of scroll position, filters and sorting when returning to lists.
• Added reasons based on actual AI lineup decisions, including rest and fatigue, to the change history.
• Added monthly development reports, accessible from Development and secretary notices. Review rating changes, development events including traits, and reserve appearances, then open a player's training screen.
• Fixed unrelated development records being cleared by player edits and incorrect batting-order history in games without a DH.
• Fixed report navigation and scrolling, and missing training-result translations.

For existing saves, rating changes are recorded from loading after the update; past changes are not reconstructed. We will keep improving usability and fixing issues.
