docs: drop the hype words from the mirrored CLI pages

[adnaan]

These four files mirror to /cli on the docs site, which now has a written voice — VOICE.md, added in livetemplate/docs#137. The docs-native pages were audited against it and came out clean. These did not.

What changed

comprehensive appeared five times and told a reader nothing. A test suite either covers the flows or it doesn't, so the text now says which:

• "generates comprehensive E2E tests using chromedp that test all auth flows" → "generates E2E tests using chromedp that cover every auth flow"
• "Each generated resource includes comprehensive tests." → "Each generated resource comes with tests."
• "A comprehensive e2e testing framework … that reduces boilerplate by 85-90%" → "An e2e testing framework … It cuts test boilerplate by 85-90%."

**Production-ready security** (HTTP-only, secure, SameSite cookies) became **Secure session cookies** (HTTP-only, Secure, SameSite) — the parenthetical was already the real claim.

Rich content popovers → Content popovers. And one nominalization: "allows you to customize templates project-wide" → "lets you customize templates across the whole project".

Left alone

Headings. Title Case is these documents' own convention, consistently applied across ~90 headings. Changing them is a rename, not a copy edit, and it would bury the actual fix in churn. Worth doing separately if you want it.

Verification

0 .go files touched — the diff is 4 markdown files. The repo's pre-commit hook (gofmt, golangci-lint, go test) ran and passed.

Reviewed — this is a small, low-risk copy edit across 4 markdown files (0 .go files touched), so most of the standard checklist (perf, security, tests) doesn't really apply. A few notes:

Discrepancy vs. the PR description
The description says headings were left alone ("Title Case is these documents' own convention... changing them is a rename, not a copy edit"), but testing/README.md does change a heading: ### Comprehensive Loggers → ### Loggers. It's harmless on its own — "Loggers" is still Title Case and consistent with the file's other ### headings — but it contradicts the stated scope. Worth either fixing the description or reverting that one hunk to match what's claimed.

Wording changes look accurate

• Spot-checked "Rich content popovers" → "Content popovers": Popover.Content (components/popover/options.go) is just a plain string field with no special "rich"/HTML handling that the old wording was uniquely describing, so dropping "Rich" doesn't lose information.
• "Production-ready security (HTTP-only, secure, SameSite cookies)" → "Secure session cookies (HTTP-only, Secure, SameSite)" is arguably more precise — capitalizing Secure matches the actual cookie attribute name rather than describing it as a vague quality.
• "Each generated resource includes comprehensive tests." → "Each generated resource comes with tests." is consistent with the nearby feature-list line ("Generated tests covering each flow") — no factual claim is lost, just the filler adjective.

Nit
docs/guides/lvt-cli-guide.md's new bullet "Generated tests covering each flow" reads slightly awkwardly sitting in a list of noun-phrase features (CRUD operations, Search across string fields, ...) — a shorter "Tests for each flow" would match the list's rhythm better, but this is a style nit, not a blocker.

Overall: solid, well-scoped edit. Only the one heading/description mismatch is worth resolving before merge.
