As per PR #5800
* DB: Planned out new entity table format via migrations
* DB: Created entity migration logic
Made some other tweaks/fixes while testing.
* DB: Added change of entity relation columns to suit new entities table
* DB: Got most view queries working for new structure
* Entities: Started logic change to new structure
Updated base entity class, and worked through BaseRepo.
Need to go through other repos next.
Removed a couple of redundant interfaces as part of this since we can
move the logic onto the shared ContainerData model as needed.
* Entities: Been through repos to update for new format
* Entities: Updated repos to act on refreshed clones
Changes to core entity models are now done on clones to ensure clean
state before save, and those clones are returned back if changes are
needed after that action.
* Entities: Updated model classes & relations for changes
* Entities: Changed from *Data to a common "contents" system
Added smart loading from builder instances which should hydrate with
"contents()" loaded via join, while keeping the core model original.
* Entities: Moved entity description/covers to own non-model classes
Added back some interfaces.
* Entities: Removed use of contents system for data access
* Entities: Got most queries back to working order
* Entities: Reverted back to data from contents, fixed various issues
* Entities: Started addressing issues from tests
* Entities: Addressed further tests/issues
* Entities: Been through tests to get all passing in dev
Fixed issues and needed test changes along the way.
* Entities: Addressed phpstan errors
* Entities: Reviewed TODO notes
* Entities: Ensured book/shelf relation data removed on destroy
* Entities: Been through API responses & adjusted field visibility
* Entities: Added type index to massively improve query speed
Ensures fields returned match API docs and previous versions of
BookStack where we were accidentally returning more fields than
expected.
Updates tests to cover many of these.
Also updated clockwork to ignore image requests for less noisy
debugging.
Also updated chapter page query to not be loading all page data, via new
query in PageQueries.
Also aligned books, shelves and chapters to return description content
and some relations (where not breaking API) in create/update responses
also so that information can be seen direct from that input in a
request.
API docs and tests not yet updated to match.
