feat: [ENG-2465] add web UI Configuration page + promote ByteRover provider onboarding

Configuration page
- Git identity panel: get/set user.name & user.email via the daemon,
  one-click seed from the signed-in ByteRover account.
- Remote panel: single `origin`, HTTPS-only validation, replace preview,
  Initialize VC CTA when git is uninitialized, "Find in ByteRover" link.
- Shared SettingsSection + CalloutRow primitives; `bg-card` alignment
  with ConnectorsPanel; skeleton loading rows.

Provider onboarding
- ByteRover pinned to top of the selector with an amber "Native" pill.
- OAuth popup opens on row click (drops the redundant login-prompt
  confirmation); 800ms minimum visible delay before popup navigates.
- ProviderFlowDialog mountable globally via provider-store so any
  surface can open it (task error CTA, etc.).

Error routing
- toastVcError maps VC config gaps to a toast action that deep-links to
  /configuration#identity or #remotes.
- Task ErrorSection shows "Configure provider" for provider-class
  errors; checks llmservice:error broadcast (task:error isn't always
  structured).
- formatError overrides aligned with Configuration page copy.

Header
- Responsive: Local badge hides <lg, HelpMenu/BranchDropdown/version
  collapse at narrower sizes, provider label truncates by breakpoint.
- StatusDot primitive (tone + pulsing) — pulsing amber when
  unconfigured, green corner dot on the Plug when active.
- `brv vc init` invalidates the remote query so panel auto-refreshes.

Other
- ProjectDropdown: "Open local folder" opens OS file manager via new
  locations:reveal transport event (registry-guarded, no shell interp).
- Global toast position = top-center; removed per-call overrides.
- CSP: allow img-src https: for OAuth provider avatars.
- BRV_GIT_REMOTE_BASE_URL surfaced via config:getEnvironment for the
  Remote URL input placeholder.

Tests
- Pure util tests: detect-git-url-type, is-valid-email, validate-remote-url,
  is-provider-task-error, reveal-command.
