Ethan 782a1052c8 test: use toHaveValue() to avoid flaky parameter verification (#20990)
## Problem

The test `create workspace with default and required parameters` was
flaky because `verifyParameters` in `site/e2e/helpers.ts` didn't wait
for input values to be populated before asserting.

After PR #20710 removed classic parameters, the form now uses dynamic
parameters loaded asynchronously via WebSocket. The input field can be
visible before its value is populated.

Closes https://github.com/coder/internal/issues/1154

## Fix

Replace immediate read + assertion:
```typescript
const value = await parameterField.inputValue();
expect(value).toEqual(buildParameter.value);
```

With Playwright's auto-retrying assertion:
```typescript
await expect(parameterField).toHaveValue(buildParameter.value);
```

From [Playwright docs for
`inputValue()`](https://playwright.dev/docs/api/class-locator#locator-input-value):

> **NOTE** If you need to assert input value, prefer
`expect(locator).toHaveValue(value[, options])` to avoid flakiness. See
assertions guide for more details.

The structure of the end-to-end tests is optimized for speed and reliability. Not all tests require setting up a new PostgreSQL instance or using the Terraform provisioner. Deciding when to trade time for robustness rests with the developers; the framework's role is to facilitate this process.

Take a look at prior art in tests/ for inspiration. To run a test:

cd site
# Build the frontend assets. If you are actively changing
# the site to debug an issue, add `--watch`.
pnpm build
# Alternatively, build with debug info and source maps:
NODE_ENV=development pnpm vite build --mode=development
# Install the browsers to `~/.cache/ms-playwright`.
pnpm playwright:install
# Run E2E tests. You can see the configuration of the server
# in `playwright.config.ts`. This uses `go run -tags embed ...`.
pnpm playwright:test
# Run a specific test (`-g` stands for grep. It accepts regex).
pnpm playwright:test -g '<your test here>'

Using nix

If this breaks, it is likely because the flake chromium version and playwright are no longer compatible. To fix this, update the flake to get the latest chromium version, and adjust the playwright version in the package.json.

You can see the playwright version here: https://search.nixos.org/packages?channel=unstable&show=playwright-driver&from=0&size=50&sort=relevance&type=packages&query=playwright-driver

# Optionally add '--command zsh' to choose your shell.
nix develop
cd site
pnpm install
pnpm build
pnpm playwright:test

To run the playwright debugger from VSCode, just launch VSCode from the nix environment and have the extension installed.

# Optionally add '--command zsh' to choose your shell.
nix develop

Enterprise tests

Enterprise tests require a license key to run.

export CODER_E2E_LICENSE=<license key>

Debugging tests

To debug a test, it is more helpful to run it in ui mode.

pnpm playwright:test-ui
