feat: answer vehicle faction, guild, ally and vassal access

[XxFran10xX]

Answers VehicleFramework's new group switches (TF-Minecraft/VehicleFramework#75), so owners can let their faction, guild, allies or vassals board instead of whitelisting names one by one.

Draft until VehicleFramework 2.15.0 is released: this pins vehicleframework.version 2.15.0, so CI cannot resolve it before that release.

What it does

• Registers VehicleAccessGroups once the vehicle stage is ready, with the same readiness as the ownership authority. VehicleFramework before 2.15 has no such service; SimpleFactions then logs a warning and vehicles keep their whitelists only.
• Membership is read each time someone boards:
  • Faction: the rider is in the vehicle's faction. A pool or installation vehicle counts from its paying faction; any other vehicle from its owner character's faction.
  • Guild: the rider is in the owner's player guild, as member or leader. A faction's main guild never counts (it is the whole faction), and faction vehicles have no guild.
  • Allies: the vehicle's faction has an ally relation with the rider's faction.
  • Vassals: the rider's faction is a direct vassal of the vehicle's faction.
• Faction vehicles always admit their own faction. Today all four faction vehicles on Main (The_Bog's gunboat, locomotive, passenger car and coal car) have their whitelist on, and the leader cannot edit it, so only the leader can board them.
• On pool and installation vehicles the leader may now turn the Allies and Vassals switches on or off. Every other control stays refused, including Faction and Guild.

Also drops LegacyVehicleClaimsOff. It only ran with VehicleFramework before 2.13, and building against 2.15 is impossible with it because VehicleFramework #72 removed VehicleOwnerClaimedEvent.

Testing

• Changed test classes pass locally (VehicleGroupAccessTest, VehicleOwnershipServicesTest, VehicleOwnershipGateTest, VehicleClaimsOffTest, LeaderStampsTest, VehicleOwnerWritesTest), and the new and changed classes have no missed lines. The full suite can't run on Windows any more (DurableJson fsyncs a directory, which Windows refuses), so CI is the full run.
• TFMCDev01 with three real character bots, this build and the VehicleFramework branch: the menu names Thalendor on the Faction switch; a Thalendor member is refused, then boards and drives once Faction is on; a stranger stays out; leaving Thalendor removes access at once; a cart registered as a Thalendor pool vehicle was restamped to Thalendor's leader and admitted a Thalendor member with no switch on, while a non-member was refused.

📝 Summary

Summary by CodeRabbit

• New Features
  • Vehicles can now support access based on faction, guild, ally and vassal relationships, alongside existing access controls.
  • Faction vehicle owners can change ally and vassal access settings.
• Bug Fixes
  • Vehicles retain whitelist-only access when group-based access is unavailable.

The plugin adds a vehicle access-group provider based on faction and guild membership. It registers the provider when the VehicleFramework API is available, permits ally and vassal access-toggle changes for faction vehicles, and updates modern and legacy claim-event registration.

Changes: Vehicle ownership and access

Layer / File(s)	Summary
Access provider and registration pom.xml, src/main/java/net/tfminecraft/simplefactions/vehicles/owners/VehicleGroupAccess.java, src/main/java/net/tfminecraft/simplefactions/vehicles/owners/VehicleOwnershipServices.java, src/main/java/net/tfminecraft/simplefactions/SimpleFactions.java, src/test/java/net/tfminecraft/simplefactions/vehicles/owners/VehicleGroupAccessTest.java, src/test/java/net/tfminecraft/simplefactions/vehicles/owners/VehicleOwnershipServicesTest.java, src/test/java/net/tfminecraft/simplefactions/PluginLifecycleCoverageTest.java	The VehicleFramework version changes to 2.15.0. VehicleGroupAccess checks faction, guild, ally, and vassal access and describes the applicable group. The plugin registers the provider when the API is available. Tests cover membership, faction-pool vehicles, readiness, and service registration.
Faction-vehicle leader switches src/main/java/net/tfminecraft/simplefactions/vehicles/owners/VehicleOwnershipGate.java, src/test/java/net/tfminecraft/simplefactions/vehicles/owners/VehicleOwnershipGateTest.java	Faction-vehicle ownership changes and non-menu edits allow ally and vassal access toggles. Other non-menu actions remain denied, and stale-stamp checks remain. Tests cover ownership changes, claim-fee events, and edit checks.
Claim-event registration src/main/java/net/tfminecraft/simplefactions/vehicles/owners/VehicleClaimGuards.java, src/main/java/net/tfminecraft/simplefactions/vehicles/owners/LegacyVehicleClaimsOff.java, src/main/java/net/tfminecraft/simplefactions/SimpleFactions.java, src/test/java/net/tfminecraft/simplefactions/vehicles/owners/VehicleClaimsOffTest.java	Claim guards register through the plugin manager. Registration uses the modern event when available and otherwise registers a legacy-event handler. It throws when neither supported event is available. Tests cover provider resolution and legacy-event handling.

- Around line 19-20: Update VehicleClaimGuards.create(String claimEvent) to
handle installations where VehicleOwnershipChangeEvent is absent by selecting a
legacy-compatible guard based on the supported VehicleOwnerClaimedEvent, without
directly referencing that event class; ensure pre-2.13 startup does not throw
while retaining the modern guard when available.

Review comments at
@src/main/java/net/tfminecraft/simplefactions/vehicles/owners/VehicleOwnershipGate.java:
- Around line 53-55: Update VehicleOwnershipGate.LEADER_SWITCHES to resolve the
optional group-access ownership reasons at runtime rather than directly
referencing enum constants that are absent before VehicleFramework 2.15. Ignore
missing enum names and retain an immutable set of any reasons that are
available, allowing older versions to continue with whitelist-only access.
