feat: unify CardHeader padding across components

- Updated `CardHeader` padding from `pb-3` to `pb-4` in `JiraLogs`, `JiraSync`, `KanbanColumn`, `ObjectivesBoard`, and `DesktopControls` for consistent spacing.
- Refactored `DesktopControls` and `KanbanFilters` to utilize new `ControlPanel`, `ControlSection`, and `ControlGroup` components, enhancing layout structure and maintainability.
- Replaced button elements with `ToggleButton` and `FilterChip` components in various filter sections for improved UI consistency and usability.
