feat(dossiq): declare ticket to dossiq as a case type

[rubenvdlinde]

Declares pipelinq's ticket to dossiq as a case type. A ticket is a case: dossiq owns case management, and pipelinq contributes the kind of work it handles rather than running a parallel system that merely resembles one.

Pairs with ConductionNL/dossiq#1646, which adds the registry that discovers this.

The class is deliberately plain

Dossiq finds it by convention FQCN (OCA\{App}\Dossiq\CaseTypeContributionProvider) and duck-types it via method_exists(), never instanceof — the same mechanism portaliq uses for PortalContributionProvider (ADR-046).

So: no dossiq imports, no implements, no info.xml dependency, no constructor dependencies. Without dossiq installed the class is inert and pipelinq behaves exactly as before, which is what { "id": "dossiq", "required": false } in the manifest promises.

An interface would read better and would make pipelinq hard-depend on dossiq. That is the coupling the pattern exists to avoid.

One case type, not three

The three ticket kinds stay one case type with a ticketType discriminator, mirroring the storage: unify-ticket-supertype folded request, complaint and interaction into a single ticket schema keyed by that field. Declaring three case types would re-split, on dossiq's side, exactly what that change joined.

Verified

5/5 tests, and they guard the contract rather than an interface no compiler enforces:

• the class takes no constructor dependencies and imports nothing
• the probed method keeps its name
• ticket carries the identifier and title the registry requires
• the three kinds stay subtypes of one case type

Worth recording from the mutation run: renaming getCaseTypes to getCasetypes does not fail these, because PHP method names are case-insensitive and method_exists still matches. A genuine rename fails 3 tests. So casing drift there is harmless; a real rename makes the provider silently invisible, with nothing in any log naming pipelinq.

phpcs clean. Committed through the GitHub API because another session holds 75 files of in-flight e2e work in the local checkout.
