Devin FoleyandPaperclip 0b945f449b Make streamlined sidebar default to on (#8496) ...

## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - The board UI has an experimental streamlined left navigation mode
that changes how projects and agents appear in the sidebar.
> - Today that mode is opt-in, so users keep seeing the classic
navigation unless they find and enable the experiment.
> - The requested product behavior is to make streamlined navigation the
default experience while keeping an explicit experiments opt-out.
> - This pull request flips the shared/server default, updates UI
consumers to treat only explicit `false` as classic mode, and covers
both the default-on path and opt-out behavior in tests.
> - The benefit is that new and legacy settings get the streamlined
sidebar by default without removing the classic-sidebar escape hatch.

## Linked Issues or Issue Description

Refs #7645

Related: #8430 takes the broader route of removing the classic sidebar.
This PR intentionally keeps the opt-out path.

## What Changed

- Default `enableStreamlinedLeftNavigation` to `true` in shared
validation and server-side normalization.
- Preserve explicit stored `false` as the experiments opt-out for the
classic sidebar.
- Render the sidebar and experimental settings toggle as streamlined-on
unless the setting is explicitly `false`.
- Add regression coverage for loading/default streamlined sidebar
behavior and the opt-out patch from the experiments page.
- Remove internal issue identifiers from newly touched source comments
before publishing.

## Verification

- `git diff --check origin/master...HEAD` — passed.
- `pnpm -r typecheck` — passed.
- `pnpm exec vitest run
server/src/__tests__/instance-settings-service.test.ts
ui/src/components/Sidebar.test.tsx
ui/src/pages/InstanceExperimentalSettings.test.tsx` — passed, 3 files /
27 tests.
- `pnpm build` — passed, with existing Vite/CSS/chunk-size warnings.
- `pnpm test:run` — failed in unrelated
`server/src/__tests__/workspace-runtime.test.ts`: the test `auto-detects
the default branch via symbolic-ref when origin/HEAD is set` creates a
temp repo on `main` then runs `git push -u origin main master`; `master`
does not exist in that temp repo. Summary: 1 failed, 214 passed, 1780
tests passed, 1 skipped.

## Risks

Low-to-medium behavioral risk: the default sidebar changes for users who
never explicitly set the experiment. Explicit `false` remains respected,
so users can still opt out via experimental settings.
