Fix/override any types

[Fayupable]

Closes #19289.

✨ Description

Replaces all 40 explicit any types in the ui/src/override directory with real types, as part of the [EPIC] Replace explicit any with real types across the frontend (#19266) initiative.

• stores/auth.ts (15): the OSS no-op permission stubs now type their permission/action/namespace parameters as string, matching how resource.ts/action.ts are already typed elsewhere in the codebase (confirmed against the merged fix(triggers) PR refactor(triggers): type the two trigger tables against the SDK models #19230, which uses the same string convention for action parameters).
• services/flowAutoCompletionProvider.ts (10): introduced a ParsedFlow interface for the parsed-YAML shape passed around the autocompletion methods, typed the YAML map helpers against YAMLMap from the yaml package, and dropped two casts (schema as any, .catch() as any) that were unnecessary — the underlying types (JSONSchema, PluginComponent) already covered the accessed fields.
• components/useLeftMenu.ts (2): menu icon element/class typed as Component/string.
• stores/misc.ts (1): configs typed with the generated SDK type MiscControllerConfiguration instead of Record<string, any>.
• components/flows/blueprints/BlueprintDetail.vue (8): reuses BlueprintType/BlueprintKind/BlueprintTag from the blueprints store instead of casting to any (exported BlueprintKind, which existed but wasn't exported).
• components/flows/Actions.vue and components/namespaces/Actions.vue (1 each): onSelectDashboard value typed as string.
• components/flows/blueprints/Blueprints.vue (1): the loaded event never actually carries a payload (the underlying BlueprintsBrowser emits it with no argument), so the emit signature was corrected to [] instead of forwarding an untyped $event.
• components/namespaces/Namespaces.vue (1 real fix + 1 dead-code removal): removed a :props="{class: 'tree'} as any" binding on KsTree that never matched the component's actual props shape and had no corresponding CSS rule (confirmed dead), and typed the namespace-hierarchy builder's intermediate map as Record<string, Node> instead of lying about it being Node[].

Every change was verified against real types read from the SDK / design-system / dependency sources (not guessed), and cross-checked against how the epic's already-merged PRs (#19230, #19227) typed equivalent patterns.

🎨 Frontend Checklist

• Type checking passes (npm run check:types)
• Code builds without errors (npm run build)
• Unit tests pass (npm run test:unit) — 256 files / 2281 tests passed
• Translations are complete if en.json changed — not applicable, no translation file touched
• Screenshots or video recordings attached — not applicable, this is a types-only change with no UI/behavior difference

📝 Additional Notes

• No runtime behavior changes anywhere in this PR — every fix is a type annotation, a cast replaced by a narrower cast/type, or the removal of confirmed dead code (the KsTree :props binding, the unused Blueprints.vue event payload).
• stores/blueprints.ts has one line changed outside the issue's file list: BlueprintKind was made exported (it existed already, just wasn't exported) so BlueprintDetail.vue could reuse it instead of duplicating the same union type.
• npm run check:types (the stricter --build project-references check) caught 5 real type errors in flowAutoCompletionProvider.ts that plain vue-tsc --noEmit had missed — all fixed and verified (undefined-filtering on mapped arrays, an explicit string cast where a truthy-narrowed unknown collapsed to {}, and a this-context cast for a Pinia store method whose wrapped/unwrapped Ref types don't structurally match even though they're the same object at runtime).
• check:types on this branch also reports 4 pre-existing errors (FilePreview.vue, FilePreviewForm.vue, TaskRunActions.vue, Secrets.vue) that are unrelated to this PR — confirmed via git diff develop...fix/override-any-types --stat on those files, which shows zero diff. They already exist on develop and are out of scope here.

Saw the CI failure. Looking into it now, will find the issues and push a fix shortly.

Re: the check:types failure on TaskRunActions.vue(175,63) — I looked into where it comes from: this file uses the generic useRoute(), whose params type always resolves every key to string | string[] (vue-router's default typing when typed routes aren't used, regardless of the actual route pattern). That value is passed straight into authStore.user?.isAllowed(resource.FLOW, action.VIEW, route.params.namespace), whose third parameter expects a plain string | undefined.

I confirmed this is pre-existing on develop and unrelated to this branch (checked out develop with none of this PR's commits, error is already there).

I wasn't sure of the right fix here — whether namespace should be normalized to a single string before this call (e.g. Array.isArray(...) ? ...[0] : ...), whether this component should use a typed route instead of generic useRoute(), or something else entirely — so I didn't want to guess and touch code outside this issue's scope. Happy to fix it here if someone can point me at the intended approach.
