SDK pages: Java pins 0.7.0, PHP $_ENV, readonly claim, JS .env, no sendEmail/createSigningUrl in turbosign.md #220

• docs(sdks): fix Java pin, PHP getenv config, readonly claim, JS .env; add send-without-emails section #229

What's wrong (Docs origin/main, docs/SDKs/)

1. java.md pins 0.7.0 at :35 (Maven), :43 (Gradle Kotlin) and :50 (Gradle Groovy). The published version is 0.8.0.
2. php.md:60-63 reads config from $_ENV, which is empty on stock PHP (variables_order = "GPCS"), so the SDK throws on missing credentials. Use HttpClientConfig::fromEnvironment() or getenv().
3. "readonly classes" is a PHP 8.2 feature, but the SDK requires PHP ^8.1 (php.md:42, turbosign.md:210).
4. javascript.md:105-109 .env example omits TURBODOCX_SENDER_EMAIL, which the SDK requires (dist/http.js:126 throws without it).
5. turbosign.md never shows sendEmail: false or createSigningUrl in any language tab (JS, Python, Go, PHP, Java). They're only documented under the embedded-signing pages, so someone reading the main TurboSign SDK page can't find the "send without emailing, hand out the link" flow.

Suggested fix

Bump the Java snippets, switch the PHP config example to fromEnvironment(), correct the readonly claim, add the sender email to the JS .env, and add a short sendEmail + createSigningUrl subsection (with the "Enable identity verification" prerequisite) to turbosign.md.

Severity: S3. Found while building the per-language "How to Sign Documents" videos (TurboVideos#8); each confirmed by an independent audit.
