ref(constants): use evo manager path helpers

[middleDuckAi]

Problem

Issue #2238 is broader than one safe PR. After the bootstrap/runtime slice, manager path and URL helpers were still using legacy MODX_* constants across core helpers and manager frame views.

Why this approach

This keeps the migration incremental:

• switch canonical core manager path/url helpers to EVO_*
• update manager frame/views to publish and consume EVO_* first
• keep compatibility aliases where frontend runtime still expects MODX_*

What changed

• updated Path, Settings, ManagerTheme, ManagerActions, Frame, and Users\\LogInOut to use EVO_* manager/site/base constants
• updated manager frame and tree views to emit EVO_* URLs and keep MODX_* JS aliases for compatibility
• updated document view/preview manager surfaces to use EVO_SITE_URL
• added regression coverage for manager path/url helper usage

Files / surfaces

• core manager path/url helpers
• manager frame runtime constants
• manager tree and preview view URLs
• targeted unit coverage for manager constant usage

Verification

• ./vendor/bin/phpunit tests/Unit/ManagerPathConstantUsageTest.php
• ./vendor/bin/pest tests/Feature/ModifiersTest.php
• php -l on touched files
• local runtime smoke check on the task branch

Risks

This is still only a bounded slice of #2238. Legacy aliases stay in place where needed so existing manager JS keeps working while the codebase shifts to canonical EVO_* constants.
