## What kind of change does this PR introduce?
Feature restoration
## What is the current behavior?
Incident banners cannot be dismissed by users.
## What is the new behavior?
Users can dismiss incident banners again.
## Additional context
Feature enhancement — smarter incident banner targeting logic
## What is the current behavior?
Displaying the incident banner requires toggling a flag or environment
variable. Banners are shown to all users regardless of whether their
projects are in affected regions or whether the incident affects project
creation.
## What is the new behavior?
Banner visibility is now driven by `show_banner` metadata from the
StatusPage API — no manual flag or env var toggle needed. Per-user
targeting is then applied:
- Users with projects only see the banner when they have a database in
an affected region
- Users without projects only see the banner when the incident affects
project creation
Incident responses are enriched with cache data (`affected_regions`,
`affects_project_creation`) fetched from a Supabase table. Visibility
logic is extracted into a dedicated hook and pure utility function,
backed by unit tests.
## Additional context
Resolves FE-2562
## 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)
