Style: chips toolbar compact design with bootstrap specificity fix

- Add bootstrap specificity overrides for input/select in chips toolbar
- Use #content.bootstrap selector with doubled classes for specificity
- Reduce toolbar height with consistent padding (0.2rem vertical)
- Change border-radius from pill to subtle rounded corners
- Simplify input structure (embedded search icon via background)
- Align all toolbar elements (input, select, count, clear button)
