Deployment custom visualizations

[safoinme]

Describe changes

• extend the deployment domain models and API surface to represent curated deployment visualizations, including request/update/response models and filter support.
• persist curated visualizations by introducing the corresponding SQLModel schema, Alembic migration, and REST/SQL store logic, and wiring the new routes into the FastAPI server.
• expose client helpers so SDK users can add, list, update, and delete the curated visualizations associated with a deployment while keeping responses hydrated with attached artifacts.

Why

• product teams need a first-class way to curate which artifact visualizations show up alongside a deployment so dashboards can surface the right insights without manual filtering.
• storing these curation decisions in the backend ensures they survive across sessions, are shareable across users, and can participate in RBAC/project scoping.
• wiring the API through the client and stores keeps the SDK in sync with the server capabilities, enabling immediate consumption by CLI/UI flows.

This is related to #4007 and the Custom visualisation ticket in Notion

Pre-requisites

Please ensure you have done the following:

This feature has the potential of becoming more than just a deployment association. In fact, I would even say that attaching visualizations to deployments is the least useful of the possible range of associations that can happen at pipeline, pipeline run and pipeline snapshot level.

If it's not too late, I'll still recommend that this be implemented using a more generic and extensible approach, similar to how run metadata is implemented (see RunMetadataResourceSchema).

This looks mostly great and I love how extensible you've made it. That being said, I do have a couple of high-level comments that will require you to change things a bit:

1. the CuratedVisualization models and Client methods don't reflect the UX expectations (see my comments)
2. you still need to add support in the schema for all the various resources

[stefannica]

The RBAC permission checks look good now, but I discovered another problem with how the SQL schemas are implemented: they are over-engineered and the foreign relationships still need some work.

The last round.
