Description

This PR improves the Kanban board behavior for large ticket sets.
The board now loads an initial batch per status and fetches additional cards progressively, while preserving the full ticket totals in each column header.
It also improves drag-and-drop handling by tracking source/target status more explicitly and updating affected column counts locally after ticket movement.

• Fixed Kanban ticket movement behavior so tickets do not unintentionally move between project columns/statuses.
• Added progressive Kanban loading with a dedicated load endpoint and reusable ticket card partial to improve board performance on large projects.
• Fixed Kanban column header counts to use server-side status totals immediately, instead of counting only currently rendered/lazy-loaded cards.
• Updated HR/SR status-change messaging translations.
