The top bar grew vertically on narrower viewports when the environment
badge and company-selector labels wrapped, pushing content under the
fixed navbar (which the layout offsets with a fixed pt-16).
Rework the navbar into a fixed h-16 row with a priority-based responsive
layout:
- search fills the middle (flex-1) and shrinks first when space is tight
- company selector holds its size and truncates long names
- environment badge degrades full pill -> compact letter badge -> hidden
- harmonize control heights (40px controls, 32px badge/avatar accents) so
the search no longer renders as a cramped thin strip
