## What kind of change does this PR introduce?
Refactor. Follow-up to #49871.
## What is the current behavior?
Branded (green) text still uses the `text-brand` classname while the
colour comes from `--primary`.
## What is the new behavior?
**Rename-only:** `text-brand` → `text-primary` across callsites and
docs. Leftover `bg-brand` / `border-brand` alias to `brand-default`. No
intentional colour changes in this PR.
This better matches how we treat our green in other components and
props, like `variant="primary"` for green buttons.
## To test
On light mode: smoke-test that branded text still looks like #49871
(readable green, not the bright fill).
-
[Homepage](https://zone-www-dot-com-git-dnywh-depr-316-text-brand-de2380-supabase.vercel.app/):
“Scale to millions” uses `text-primary`
- [Docs
homepage](https://docs-git-dnywh-depr-316-text-brand-to-primary-supabase.vercel.app/docs):
branded links like “More on self-hosting” are still readable
- [Typography
docs](https://design-system-git-dnywh-depr-316-text-brand-to-primary-supabase.vercel.app/design-system/docs/typography):
documents `text-primary`
- [Colour
usage](https://design-system-git-dnywh-depr-316-text-brand-to-primary-supabase.vercel.app/design-system/docs/color-usage):
`text-primary` is visibly darker than `bg-brand-default` _on light mode_
- [Studio auth
providers](https://studio-staging-git-dnywh-depr-316-text-brand-to-60fa6c-supabase.vercel.app/dashboard/project/_/auth/providers):
enabled provider badge text readable; status dot stays bright green

## Problem
Auth overview error tables call the legacy logs endpoint through
fetchLogs defaults, even with the ClickHouse migration enabled.
Success-rate cards also show zero when there are no requests and
misleading relative changes between small rates.
## Fix
Select matching BigQuery or ClickHouse queries with otelLegacyLogs,
separate caches by engine, and normalize numeric results.
Show No data for success rates without requests and omit comparisons
when either period has no requests. Show success-rate changes in
percentage points: 0% to 0.2% displays +0.2 pp. Omit undefined relative
changes from a zero baseline for activity and sign-up counts. Show
explicit errors for failed log requests, including error payloads
returned with HTTP 200, instead of empty tables.
## Validation
- Auth overview error tables compared against staging with matching
data.
- 84 focused tests passed across four suites, including 25 direct
formatter tests.
- 12 MSW integration tests exercise both endpoint/SQL pairs, HTTP and
embedded API failures, and rendered No data, genuine 0%, and +0.2 pp
states.
- Unit tests cover missing periods, zero requests, percentage-point and
relative changes, SQL structure, and numeric result parsing.
- Formatting and diff checks passed; code review found no actionable
issues.
- Full local lint/typecheck are limited by shared checkout dependencies.
Browser comparison confirmed the deployed rate display uses percentage
points and shows No data without a comparison for absent server
requests; populated error rows match staging. The final formatter
extraction (9886b78682) was also deployed and verified in the browser;
CI completion remains outstanding.
Split from #50173.
