## What kind of change does this PR introduce?
Bug fix / design-system alignment for the legacy `Button` from `ui`.
## What is the current behavior?
Omitting `variant` on the legacy `Button` falls back to brand-green
`primary`. That makes accidental greens easy, and it is hard to spot the
real main action on busy pages.
## What is the new behavior?
- Legacy `Button` now defaults to neutral `default`
- Intentional primary CTAs (create, save, submit, marketing CTAs, and
matching `ButtonTooltip` usages) now set `variant="primary"` so their
appearance is unchanged
- Neutral actions that previously relied on the old fallback (cancel,
close, back, dashboard nav, and similar) become grey/white
- Design-system docs updated; regression tests cover the new default
`Button_Shadcn_` is unchanged. It already uses its own CVA default.
This is PR 1 of 2 in a stack. PR 2 drops now-redundant
`variant="default"` props.
## To test
Studio (http://localhost:8082):
- `/sign-in`: Sign in stays green
- Open a project → Database → Tables: New table stays green
- Auth → Users → Invite: Invite user stays green; Cancel / dismiss
controls stay neutral
- Project Settings → General: edit a field so Cancel and Save appear.
Cancel is neutral, Save is green
Design system (http://localhost:3003):
- Components → Button: default demo is neutral; primary demo is green;
featured preview is the default variant
Marketing (optional):
- www header: Start your project stays green; logged-in Dashboard is
neutral

## Summary by CodeRabbit
- **Style**
- Buttons now default to a neutral style, while primary actions across
Studio, documentation, marketing pages, forms, dialogs, and error states
use prominent primary styling.
- Updated button examples and previews clarify the distinction between
default and primary variants.
- Event registration now includes a directional arrow icon.
- **Tests**
- Added coverage confirming default button styling and explicit primary
styling behave as expected.
- Updated related test fixtures to use primary styling where
appropriate.

## Summary
- define application-owned database and logs source contracts, defaults,
validation, labels, and execution endpoints
- extract controlled database and logs parameter controls for reuse
outside SQL snippets
- adapt the SQL editor to the shared source model without changing
snippet behavior
- standardize source icons at 16px with a 2px stroke
- keep relative logs ranges aligned with the existing date picker units
## To test
1. Open an existing query in the SQL Editor and run it against the
database.
2. Switch the query source to Logs, change the time range, and confirm
the query still runs as expected.
## Why
Explorer queries and notebook query cells need to select an execution
source without coupling that source to SQL snippets. This provides the
shared registry and controlled UI foundation for those consumers.
## Impact
Existing SQL snippets retain their current database/logs routing and
session behavior. The registry documents the SQL editor legacy
database-selector adapter while new consumers own their identifier
inline. The shared Logs date picker remains unchanged; query ranges
support its existing minute, hour, and day units. This PR does not add
the Explorer query tab itself.
## Validation
- pnpm --filter studio typecheck
- focused Vitest coverage for the registry, canonical log-range
utilities, SQL execution adapters, source filtering, retention locking,
custom ranges, and preset selection
- pnpm --filter studio run lint:ratchet
Component and state tests cover this change per the Studio testing
guidance; no E2E test is added.
