Add enable/disable functionality for custom templates

[Tharanidk]

Purpose

Previously, enable/disable was restricted to built-in templates only. This PR allows custom templates to be toggled as well, since enable/disable only affects control-plane listing.

Changes

• platform-api: remove the managedBy restriction in SetVersionEnabled so custom templates can be enabled/disabled. Disabling is still blocked when the version is in use by a provider.
• AI Workspace: show the enable/disable switch for all templates, not just read-only ones.
• Provider template list: fetch all versions (not just the latest) so each family card shows the highest enabled version, falling back to the highest version with disabled styling when the whole family is disabled.

Resolves: #2692

📝 Walkthrough

Walkthrough

Custom template versions can now be enabled or disabled. The AI Workspace retrieves all template versions, selects versions per ownership and family based on enablement and version, and displays toggle controls for all template origins.

Changes

Custom template enablement and version selection

Layer / File(s)	Summary
Custom template toggle service and validation platform-api/internal/service/llm.go, platform-api/internal/service/llm_provider_template_test.go, platform-api/internal/handler/llm_template_integration_test.go	SetVersionEnabled permits custom templates, preserves the in-use check when disabling, and tests successful and blocked custom-template toggles through service and HTTP coverage.
All-version retrieval and family selection portals/ai-workspace/src/apis/providerTemplateApis.ts, portals/ai-workspace/src/pages/appShell/appShellPages/providerTemplate/ProviderTemplatesList.tsx	The API client can request all versions, while the list groups templates by ownership and family and selects the highest enabled version or highest-version fallback.
Version enablement controls portals/ai-workspace/src/pages/appShell/appShellPages/providerTemplate/ProviderTemplateOverview.tsx	Enable/disable labels and switches are rendered for built-in, custom, and gateway-originated templates.

136-171: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Duplicate version-parsing/comparison logic across files.

parseVersion/isHigher here duplicates the same "parse v<major>.<minor> and compare" logic already implemented separately as parseVerNum in ProviderTemplateOverview.tsx. Extracting a shared compareTemplateVersions/parseTemplateVersion utility (e.g. alongside familyHandle in providerTemplateDisplay.ts) would prevent the two implementations from silently diverging as version semantics evolve.
