Exponential Platform Nexus Files

Release of the 1.3.0.x line: Platform v5 with Symfony 7.4, without the legacy kernel. Changes since 1.3.0.5.

Before installing: run composer update se7enxweb/exponential-platform-dxp-core to get v5.0.9 (Layouts schema fix). The lock file of this release still pins v5.0.7, whose installer does not create the Netgen Layouts tables for the se7enxweb/layouts-core fork, so the demo data then fails with no such table: nglayouts_....

Code fixes

• TRUSTED_PROXIES sets the proxies Symfony trusts, in config/packages/framework.yaml (4eb6eb6dd).
• APP_HTTP_CACHE=1 puts the Symfony HTTP cache proxy in front of the kernel; it is off by default (ac3f43a74).
• config/app/server/prod.yaml exists, so SERVER_ENVIRONMENT=prod builds (88c4a4b35).
• make reindex and the Deployer reindex task call exponential:reindex. ibexa:reindex does not exist on this line (1635061cf).
• public/index_cluster.php works without a legacy root (7a91abb3c), and public/index_rest.php has a safe fallback (694a94004).
• composer.json names the package se7enxweb/exponential-platform-nexus and states the licence GPL-2.0-or-later; it had no name and said "proprietary". The content hash in composer.lock follows (e329bcb0f).
• LICENSE, with the GPL version 2 text, is back; it had been removed with the move to v5 (695373c72).
• The admin UI config sets defaults for content_tree_module (df4925471).
• Makefile: make clear-all-cache empties the configured cache pools (19fb97537), and the .nvmrc version is passed to nvm install (3cd84213c).

Documentation

• The book (doc/book/, a copy from master): it covers every release line, and the newest copy is on master. doc/INSTALL.md is new, the short installation guide.
• doc/sevenx/INSTALL.md and README.md were corrected:
• The siteaccesses are fh_eng, bold_eng, bold_ger and adminui.
• The guide no longer promises ibexa: aliases for the exponential: commands.
• The reindex examples use a content type the demo has.
• The HTTP cache is purged by tag, and the guide points at the shipped Varnish VCL.
• The image variations are in config/app/packages/image.yaml.
• The database is configured through DATABASE_URL, with grants that work on current servers.
• The REST API is at /api/ibexa/v2/ and uses the session.
• doc/netgen/IBEXA_MIGRATIONS.md names the migration bundle this line installs.
• Server examples: the nginx example uses a PHP 8.4 socket and APP_ENV prod, and the Apache example describes APP_HTTP_CACHE correctly.
