feat: migrate scripture settings to ScriptureLinks plugin

[bcordis]

Summary

Moves scripture provider settings from Proclaim's component params (#__bsms_admin.params) to the ScriptureLinks plugin params (#__extensions.params). The scripture system becomes self-contained — install the library + plugin and you get full scripture functionality without Proclaim.

Architecture

• Plugin params own all scripture config (providers, API key, cache, default version)
• Library owns ScriptureParamsHelper for reading/writing plugin params, shared form fields, and the TranslationsmanagerField renderer
• Proclaim embeds the Scripture tab via TranslationsmanagerField::renderScriptureTab() — single shared renderer for identical UI on both plugin and Proclaim admin pages
• GDPR mode syncs bidirectionally — Proclaim keeps its own copy for analytics/privacy, plugin keeps its copy for scripture API calls

Changes

Library (CWMScriptureLinks submodule)

• ScriptureParamsHelper — read/write plugin params from #__extensions
• ApiKeyField + BibleTranslationField — moved to library namespace
• TranslationsmanagerField — complete Scripture tab UI (panels + translations table)
• bible-translations.js + cwm-fetch.js — copied to library media
• Plugin AJAX handler with 9 Proclaim actions + 3 plugin-native actions
• Removed BibleGateway external links — all display modes use local/API text
• Attribute-style tag syntax: {scripture display="tooltip" version="kjv"}...{/scripture}

Proclaim

• Admin Center Scripture tab calls shared renderer (replaces ~130 lines of template HTML)
• CwmadminModel intercepts save to redirect scripture params to plugin
• bible-translations.es6.js AJAX URLs use com_ajax instead of com_proclaim
• Controller: removed ~630 lines of scripture AJAX methods
• Form fields: thin backward-compat wrappers delegating to library
• Migration script copies params from component to plugin on upgrade
• Library manifest symlinked for namespace autoloading

Test plan

• Plugin standalone: Configure scripture settings via Extensions > Plugins > ScriptureLinks. Add {scripture}John 3:16{/scripture} to an article. Verify passage renders.
• Proclaim admin: Scripture tab displays current plugin settings. Toggle providers, change defaults, save. Verify changes persist in plugin params.
• AJAX endpoints: Local Translations panel loads, download/remove/sync all work via com_ajax URLs.
• GDPR sync: Change GDPR mode in plugin → verify Proclaim picks it up. Change in Proclaim → verify plugin picks it up.
• Migration: Install upgrade on a site with existing scripture settings. Verify settings migrated from component to plugin params.
• Fresh install: New Proclaim install registers plugin with default settings. Scripture tab works immediately.
• composer test: All PHPUnit + Jest tests pass.
