feat(canvas+workspace-server): data-driven Provider dropdown (#199)

Option B PR-5. Canvas Config tab now exposes a Provider override input
that's adapter-driven from each runtime's template — no hardcoded
provider list in the canvas. PUT /workspaces/:id/provider on Save
when dirty; auto-restart suppression to avoid double-restart with
the model handler's own restart.

The dropdown's suggestion list comes from /templates →
runtime_config.providers (the field added in
molecule-ai-workspace-template-hermes PR #31). For templates that
haven't migrated to the explicit providers list yet, suggestions
derive from model[].id slug prefixes — still adapter-driven, just
inferred. This keeps existing templates working while platform team
migrates them one at a time.

workspace-server changes:
- Add Providers []string field to templateSummary JSON
- Parse runtime_config.providers in /templates handler
- 2 new tests pin the surfacing + omitempty behavior

canvas changes:
- Remove hardcoded PROVIDER_SUGGESTIONS constant
- Add provider/originalProvider state + PUT-on-save logic
- Add deriveProvidersFromModels() fallback helper
- Wire RuntimeOption.providers from /templates response
- 8 new tests pin the behavior end-to-end

// Regression tests for ConfigTab Provider override (Option B PR-5).
//
// What this pins: a free-text Provider combobox in the Runtime section
// that lets the operator override the model→provider derivation hermes-
// agent does internally. Without this UI, a fresh signup whose Hermes
// workspace defaults to a model with no clean vendor prefix (e.g.
// `nousresearch/hermes-4-70b`) hits the runtime's own preflight error:
// "No LLM provider configured. Run `hermes model` to select a
// provider, or run `hermes setup` for first-time configuration."
// — even though tasks #195-198 wired the entire downstream pipe so a
// non-empty provider WOULD flow through canvas → workspace-server →
// CP user-data → workspace config.yaml → hermes adapter.
//
// Hongming Wang hit this on hongming.moleculesai.app at signup
// 2026-05-01T17:35Z. Backend PRs were green, the gap was the missing
// UI to set the value.
//
// Each test pins one invariant. If any fails, the bug is back.

// populate the Provider override dropdown WITHOUT hardcoding any
// provider taxonomy on the frontend — that's the "data-driven from

//
// If a future yaml-tag rename or struct edit drops the field, every
// runtime would silently fall back to model-prefix derivation. For
