feat(drt): config-based prebooking logic per DRT mode (#4545)

[samuelhoenle]

Issue

When using multiple DRT modes with prebooking, ProbabilityBasedPrebookingLogic and AttributeBasedPrebookingLogic can only be installed programmatically via controller.addOverridingQSimModule(). The probability and submissionSlack values are passed as constructor arguments, with no way to set them per-mode in config.xml.

Closes #4545

Change

Following @sebhoerl's suggestion, this adds two new nested parameter set types inside <parameterset type="prebooking">:

<parameterset type="prebooking">
  <parameterset type="logic:probability">
    <param name="probability" value="0.5" />
    <param name="submissionSlack" value="900.0" />
  </parameterset>
</parameterset>

or

<parameterset type="prebooking">
  <parameterset type="logic:attributes">
    <param name="submissionTimeAttributePrefix" value="drtSubmissionTime" />
    <param name="plannedDepartureTimeAttributePrefix" value="drtPlannedDeparture" />
  </parameterset>
</parameterset>

When a logic parameter set is present in config, DrtModeQSimModule auto-installs the corresponding logic -- no manual install() call needed.

Design decisions

• One-of-many pattern: Both logic param sets share a single field in PrebookingParams via addDefinition(), matching the existing pattern used by DrtConfigGroup for insertion search params. Only one logic type can be active per mode.
• Configurable attribute prefixes: AttributeBasedPrebookingLogic now supports configurable attribute name prefixes (defaults unchanged). This follows the suggestion that the attribute-based config should "just give the name of the attributes".
• Backward compatible: Existing programmatic install() calls continue to work. If no logic parameter set is configured, no logic is auto-installed.

Changed files

• PrebookingParams: register nested logic parameter sets
• DrtModeQSimModule: auto-install logic from config
• AttributeBasedPrebookingLogic: support configurable attribute prefixes

New files

• ProbabilityBasedPrebookingLogicParams, AttributeBasedPrebookingLogicParams: config classes
• PrebookingLogicConfigTest: unit tests (config round-trip, end-to-end, one-of-many constraint)

Looks great!
