Description

Re-implement the simple checkout form preset (originally in PR #740, closed due to merge conflicts with main).

What

Add a simple checkout form template where customers only enter their email address — username, password, site title, and site URL are all auto-generated server-side.

Why

PR #740 implemented this feature but was closed due to merge conflicts. The feature is valuable for reducing checkout friction. The branch feature/simple-checkout still exists and can be used as reference.

How

Reference PR #740 for the implementation approach:

• inc/checkout/signup-fields/class-signup-field-password.php — add auto_generate_password toggle
• inc/checkout/class-checkout.php — resolve password via wp_generate_password(16) when auto-generate is set; strip password validation rules
• inc/models/class-checkout-form.php — add simple to template enum and use_template()
• inc/apis/schemas/checkout-form-create.php + checkout-form-update.php — add simple to template field enum
• Add unit tests for the new template and auto-generate behavior

Acceptance Criteria

• simple template available in checkout form presets
• Customer only needs to enter email address on simple checkout
• Username, password, site title, site URL auto-generated server-side
• Client-side JS validation does not block submission when auto-generate is enabled
• All existing tests pass; new tests cover the auto-generate path
• No merge conflicts with current main

Reference

• Original PR: feat: add simple checkout form template with auto-generated credentials #740 (closed due to merge conflicts)
• Branch: feature/simple-checkout (still exists, use as reference only — do NOT reopen)

Worker exited after ~60min with 0 commits (struggle_ratio: n/a).

• Branch: feature/t524-simple-checkout
• Reason: Worker process exited without creating a PR or committing code. 2 modified test files left uncommitted in worktree.
• Diagnosis: Worker likely hit session token limit or encountered an unrecoverable error during test suite execution. The test modifications suggest it was fixing pre-existing test failures before implementing the feature.
• Next action: Re-dispatch with explicit instruction to skip test fixes and implement the checkout form template directly, referencing PR feat: add simple checkout form template with auto-generated credentials #740 for the implementation approach.
