Joshen Lim 839b367375 chore(studio): Consolidate incident banner + maintenance banner, make incident banner dismissible (#42551) ...

## Context

PR mainly adds a change to allow users to dismiss an incident banner

Am also taking this time to consolidate `IncidentBanner` and
`MaintenanceBanner` into a single component `StatusPageBanner` so that
the logic for rendering either component is more clearer.

## Intended behaviour (should be covered by e2e tests)
- Incident banner shows if there are incidents with impact !== 'none'
- Incident banner still takes precedence over Maintanence banner (if
there's both incident + maintenence events)
- Dismissing the incident banner will subsequently show the maintenance
banner if the maintenance hasn't been dismissed before (just to make
sure that the user doesn't miss any comms)
- Incident banner will not be dismissible if there's an override (via
feature flag or env var)

consolidated StatusPageBanner component.

* Added end-to-end tests covering banner visibility, precedence, and
dismissal behavior.
