Adds ClickHouse as a replication destination type in Studio.
- New ClickHouse option in the destination type selector, gated behind
the
`etlEnableClickHousePrivateAlpha` organization feature flag (off by
default).
- ClickHouse settings form: URL, user, password (optional), database,
and
- Client-side URL validation requires HTTPS and rejects URLs targeting
internal addresses (loopback, RFC 1918, link-local, CGNAT, IPv6
loopback/link-local/ULA, and IPv4-mapped/NAT64 forms). Server-side
validation remains authoritative.

## Summary by CodeRabbit
## New Features
- Added **ClickHouse** as a replication destination option (private
alpha), including support in destination selection/panel, replication
diagram rendering, and destination icons.
- Introduced a ClickHouse destination form with fields for URL, user,
optional password (masked toggle), database, and engine selection.
- Added ClickHouse destination config handling for create/update flows,
with normalization and engine support.
## Tests
- Expanded unit tests to cover ClickHouse validation and destination
config building/normalization, including HTTPS-only and blocking
localhost/internal targets.

## Details of change
Adds Snowflake to the Studio replication destination flow:
- destination selection and display
- create/edit form fields
- validate/create/update payload serialization
- generated Platform API types
Snowflake remains gated behind `etlEnableSnowflakePrivateAlpha`.
**Note:** I have configured `etlEnableSnowflakePrivateAlpha` in
ConfigCat ("all" in staging and tied to my own org id in prod).
## Details of Verification Process
- Studio focused Vitest coverage for form serialization and diagram
mapping
- Studio typecheck
- ESLint on changed Studio replication files
- Local `mise fullstack:dev` smoke test to confirm the Snowflake form
renders ok.

/>
Full create/validate E2E depends on the Platform PR and ETL runtime
rollout.
## Review Requests
Please check the Snowflake wire payload matches the Platform/ETL
contract and that gating/edit/display behavior follows the existing ETL
destination patterns.
