fix(program-list): isolate TooltipInfoService and fix signal mutation

DeatilComponent (parent) provided TooltipInfoService and used 'base' key
for the analytics button tooltip. ProgramListComponent inherited the same
instance via DI, also using 'base' — hovering either opened both.

- Add TooltipInfoService to ProgramListComponent.providers for isolation
- Replace direct signal mutation (isHintExpertsVisible()['base'] = true)
  with proper tooltipInfoService.show/hide/isVisible calls
- Remove unused isHintExpertsVisible field
- Update spec: add TooltipInfoService to overrideComponent remove list,
  extend mock with isVisible/show/hide
