chore: refresh dependencies, fix Linux tool tasks, modernize Go idioms

Frontend deps: @hookform/resolvers 5.4.0 -> 5.4.3 and react-hook-form
7.82.0 -> 7.83.0. The @typeschema/valibot override is what makes this
installable at all. Resolvers 5.4.3 re-declares 25 optional peers for its
validator matrix, and npm resolves them into the ideal tree even though none
are used here; two of them contradict, since resolvers wants valibot ^1 while
@typeschema/main -> @typeschema/valibot pins valibot ^0.39. Both target the
same node_modules/valibot, so a plain npm update dies with ERESOLVE. The
override settles that one edge and nothing extra lands in node_modules.

Backend deps: telego 1.10.0 -> 1.11.1 (Telegram Bot API v10.2, additive
only), klauspost/compress 1.19.1, plus the indirect bumps that came with them.

VS Code tasks: the golangci-lint and modernize tasks assumed Windows PATH
semantics, where PATH is a persistent user variable that every process
inherits, so ~/go/bin was always visible. On Linux that directory is exported
from ~/.bashrc, which the non-interactive `bash -c` behind a task never
sources, and both tasks failed with exit 127. Adds linux/osx option blocks
that prepend the Go bin directories and leaves the Windows path untouched,
plus tasks to install the two tools; those are split because go install
rejects packages from different modules in one invocation.

Go sources: modernize -fix output, covering range-over-int, slices.Backward,
maps.Copy, strings.CutPrefix and strings.SplitSeq. Behaviour is unchanged.

               Code changes happen only when the maintainer mentions @claude.

 Locale strings live in `internal/web/translation/<locale>.json`, **not** under `frontend/`. The Go binary embeds the same JSON and serves it to both backend templates and `react-i18next` (initialized in `src/i18n/react.ts`). When a new English key is added it must also land in **every** non-English locale — missing keys do not break the build, they just render the raw key in the UI.
 
-### Two dev workflows
+### Dev workflows
 
 | Goal | Command |
 |------|---------|
 | Iterate on UI changes with HMR | `cd frontend && npm run dev` (Vite on `:5173`, proxies `/panel/*` and the WebSocket to the Go panel on `:2053`). Start the Go panel first. |
 | Verify what end users actually see | `cd frontend && npm run build`, then `go run .`. The Go binary serves the built bundle — embedded in release mode, off disk in debug mode. |
+| Develop/preview a reusable component in isolation | `cd frontend && npm run storybook` (Storybook workbench + autodocs on `:6006`). |
 
 The Vite dev proxy serves the admin SPA for any `/panel/*` URL — `bypassMigratedRoute` in `vite.config.js` rewrites those requests to `index.html` and lets React Router take over — while forwarding `/panel/api/*`, `/panel/api/setting/*`, `/panel/api/xray/*`, and the WebSocket to the Go panel. Because routing is now client-side, new panel routes need no proxy or allowlist changes.

 - **Document new endpoints.** Every new `g.POST`/`g.GET` in `internal/web/controller/` needs a matching entry in `src/pages/api-docs/endpoints.ts` — it drives both the in-panel API docs and the generated OpenAPI/Zod (`npm run gen:api` / `gen:zod`).
 - **Do not break link generation.** Share-link logic lives in `src/lib/xray/` (`inbound-link.ts`, `outbound-link-parser.ts`, …) and is round-tripped by the golden fixture suite — run `npm run test` after any change to URL generation, defaults, or TLS/Reality handling, and regenerate snapshots (`npx vitest run -u`) only for intentional changes. Two runtime paths consume it: the **inbounds page** and the **clients page** subscription links (`/panel/api/clients/subLinks/:subId` → backend `GetSubs`); exercise both.
 - **Vite is pinned to an exact version** (no `^`) in `frontend/package.json` — read the live version there rather than trusting a number quoted here — so local, CI, and release builds resolve identically. Bump it deliberately and verify both `npm run dev` and `npm run build` afterward.
+- **Reusable components are documented in Storybook.** When you add or change a component in `frontend/src/components/`, add or update its co-located `<Component>.stories.tsx` (`tags: ['autodocs']`), documenting props via `argTypes` / `parameters.docs` string metadata rather than JSDoc. CI compile-checks every story via `npm run build-storybook` and runs each story as a headless-browser test via `@storybook/addon-vitest` (`npm run test`, needs `npx playwright install chromium`); run `npm run storybook` to preview locally.

+`@storybook/addon-a11y` flags accessibility issues in the canvas, and
+`@storybook/addon-vitest` runs every story as a headless-browser test under
+`npm run test` (Playwright/Chromium — run `npx playwright install chromium` once
+locally). The `.storybook/preview.tsx` decorator wraps every story in the AntD
+`ConfigProvider` and adds a light/dark theme toggle to the toolbar.
+
+Conventions for a story:
+
+- Co-locate it with its component as `<Component>.stories.tsx`.
+- Set `tags: ['autodocs']` so it gets a generated docs page.
+- Document props via story metadata, not JSDoc (the repo bans `//` comments): a
+  component summary in `parameters.docs.description.component` and per-prop text
+  in `argTypes[prop].description`. `satisfies Meta<typeof Component>` keeps the
+  metadata type-checked.
