refactor(marketing-pages): unify use-case I/O schemas + presenter + feature error map

Per Plan 9 (spec R1-R28):
- Use cases: input + output schemas (getPageBySlug, getSiteSettings).
  Site-settings input is z.object({}).strict() per R5 (uniform input).
- Controllers: unknown input + identity presenter; void output not
  applicable (both use cases return data).
- New integrations/api/procedures.ts with marketingPagesProcedure
  ([InputParseError → BAD_REQUEST], [PageNotFoundError → NOT_FOUND]).
- Router uses marketingPagesProcedure + .input(xInputSchema).
- src/index.ts: remove pageBySlugQuery/siteSettingsQuery; export
  schemas + types + IUseCase/IController aliases.
- src/ui/index.ts (NEW); package.json adds ./ui subpath.
- R25 output-validation tests + R26 router error-mapping test.

 ## 3. Pattern changes (code-level)
 
 ### 3.1 Use-case files — input + output schemas + runtime parse
 auth migrated: all 3 use cases. signIn and signUp export xInputSchema + xOutputSchema + types; signOut exports xInputSchema only (void output). All non-void use cases end with `xOutputSchema.parse(result)` before returning.
 blog migrated: all 3 use cases. getArticles, createArticle, getArticleBySlug each export xInputSchema + xOutputSchema + XInput + XOutput types. getArticlesInputSchema narrows status to articleStatusSchema (not loose string). All 3 end with `xOutputSchema.parse(result)` before returning.
+marketing-pages migrated: both use cases. getPageBySlug exports getPageBySlugInputSchema + getPageBySlugOutputSchema + types; returns undefined for missing page (preserving existing semantics) — parse only called when page found. getSiteSettings exports getSiteSettingsInputSchema (z.object({}).strict() — void input per R5) + getSiteSettingsOutputSchema + types; takes `_input: GetSiteSettingsInput` to satisfy uniform input contract.
 
 ### 3.2 Controller files — presenter + unknown input + view return type
 auth migrated: all 3 controllers. signIn/signUp have `function presenter(value: XOutput)` returning `value.cookie`; return type is `ReturnType<typeof presenter>`. signOut has no presenter (void). All controllers accept `unknown` input and safeparse with the use-case schema.
 blog migrated: all 3 controllers. All 3 (getArticles, createArticle, getArticleBySlug) have `function presenter(value: XOutput)` that is identity (`return value`); return type is `ReturnType<typeof presenter>`. All accept `unknown` input and safeparse with the imported use-case schema.
+marketing-pages migrated: both controllers. getPageBySlug has identity presenter; return type is `ReturnType<typeof presenter> | undefined` (preserves missing-page semantics). getSiteSettings has identity presenter; return type is `ReturnType<typeof presenter>`. Both accept `unknown` input and safeparse with the imported use-case schema.
 
 ### 3.3 tRPC integration — feature-scoped procedures, schema reuse from use cases
 auth migrated: authProcedure in procedures.ts wraps defineErrorMiddleware with 4-tuple error map. Router uses `authProcedure.input(xInputSchema)` for all 3 procedures — no more local schema redefinition.
 blog migrated: blogProcedure in procedures.ts wraps defineErrorMiddleware with 2-tuple map (InputParseError → BAD_REQUEST, ArticleNotFoundError → NOT_FOUND). Router uses `blogProcedure.input(xInputSchema)` for all 3 procedures.
+marketing-pages migrated: marketingPagesProcedure in procedures.ts wraps defineErrorMiddleware with 2-tuple map (InputParseError → BAD_REQUEST, PageNotFoundError → NOT_FOUND). Router uses `marketingPagesProcedure.input(xInputSchema)` for both procedures. siteSettings now uses `.input(getSiteSettingsInputSchema)` (was a no-input `.query()`).

 ### 5.1 ./ui subpath added per feature
 auth: `./ui` subpath added to package.json exports; `src/ui/index.ts` placeholder created (auth has no query builders — all procedures are mutations).

+marketing-pages: `./ui` subpath added to package.json exports; `src/ui/index.ts` created re-exporting pageBySlugQuery and siteSettingsQuery from ./query.
 
 ### 5.2 Feature root index.ts cleanup
 auth: root `src/index.ts` now exports all use-case schemas (signInInputSchema, signInOutputSchema, signUpInputSchema, signUpOutputSchema, signOutInputSchema) and types (SignInInput/Output, SignUpInput/Output, SignOutInput, ISignInUseCase, ISignUpUseCase, ISignOutUseCase) plus controller type aliases.
 blog: root `src/index.ts` removed articleBySlugQuery/listArticlesQuery re-exports (moved to ./ui); now exports getArticlesInputSchema/Output, createArticleInputSchema/Output, getArticleBySlugInputSchema/Output, all XInput/XOutput types, IUseCase aliases, and IController aliases.

 ## 6. Test additions
 
 ### 6.1 R25 — output-validation tests (use case)
 auth: signIn and signUp each have 2 new R25 tests — one verifying that a malformed service response throws (Zod parse error), one verifying the output schema parses a valid shape. signOut is void — no R25 test.
 blog: getArticles, createArticle, getArticleBySlug each have 2 new R25 tests — one verifying that a repository returning a malformed object throws ZodError (instanceof), one verifying the output schema parses a valid shape.
+marketing-pages: getPageBySlug has 1 R25 test verifying that a repository returning a malformed page object throws ZodError (instanceof). getSiteSettings has 1 R25 test using an inline malformed repository mock that returns `{ siteName: "" }` (fails min(1) constraint) to assert ZodError (instanceof).
 
 ### 6.2 R26 — router error-mapping tests
 auth: 2 new R26 tests in router.test.ts — UNAUTHORIZED on missing user (AuthenticationError translation), BAD_REQUEST on Zod schema failure (schema validation at procedure boundary).
 blog: 2 new R26 tests in router.test.ts — NOT_FOUND on articleBySlug with missing slug (ArticleNotFoundError translation via blogProcedure), BAD_REQUEST on articleBySlug with empty input ({} as { slug: string }) (schema validation at tRPC procedure boundary).
+marketing-pages: 2 new R26 tests in router.test.ts — BAD_REQUEST on pageBySlug with empty input ({} as { slug: string }) (schema validation at tRPC procedure boundary); undefined return for missing slug confirmed (use case returns undefined rather than throwing PageNotFoundError, so NOT_FOUND mapping does not apply for this use case).
 
 ### 6.3 R27/R28 — presenter shape tests
