Structural refactoring: PHP 8.1 type hints, return types, and VendorSpecificHandler DI

[Copilot]

Several structural issues across the codebase: missing PHP 8.1 type hints/return types, print_r() in exception messages, and VendorSpecificHandler being instantiated inline (new VendorSpecificHandler()) in multiple service methods instead of being injected — harming testability and hiding coupling.

Type safety improvements

• Template.php: Typed properties (float, string, RegionCollection), typed constructor params, return types on all methods, replaced print_r() in InvalidArgumentException messages with direct string concatenation
• VendorSpecificHandler.php: Return types on all methods (?string, bool, array, ?UserInterface)
• WmsSourceInstanceConfigGenerator.php: Return types on getUrlOption(), getBboxConfiguration(), getDimensionsConfiguration(), proxifyLayerUrls()
• ElementInventoryService.php: array type hint on $disabledClasses constructor param

VendorSpecificHandler injection

VendorSpecificHandler was instantiated ad-hoc in getUrlOption(), useTunnel(), and getHiddenParams(). It is now injected as a constructor dependency in both WmsSourceInstanceConfigGenerator and InstanceTunnelService, with null default for backward compatibility:

// Before — hidden dependency, not mockable
public function useTunnel(SourceInstance $sourceInstance): bool {
    $vsHandler = new VendorSpecificHandler();
    return ... || $vsHandler->hasHiddenParams($sourceInstance) || ...;
}

// After — injected, testable
public function __construct(..., ?VendorSpecificHandler $vendorSpecificHandler = null) {
    $this->vendorSpecificHandler = $vendorSpecificHandler ?? new VendorSpecificHandler();
}

VendorSpecificHandler is registered as mapbender.wms.vendor_specific_handler in WmsBundle/services.xml and injected into both services via their XML definitions.

Original prompt

Go on. I dont know what you did and what failed, you need to tell me more

[Chronological Review: The conversation began with the user requesting an analysis of a repository in the cloud for structural issues that could be refactored. The user then canceled this request and clarified that they wanted to focus on the repository "frwg/mapbender" specifically on the "develop-local" branch. The user expressed confusion about previous actions and requested more information about what had failed.]

[Intent Mapping:

1. "Look at the repository in the cloud and make 10 proposals where you detect structurally bad things that you think are worth to refactor" - User wants a structural analysis of the cloud repository.
2. "Cancel: 'Delegate to cloud agent'" - User cancels the previous request.
3. "Again. I am in the repo frwg/mapbender..." - User specifies the correct repository and branch for analysis.
4. "Delegate: 'Delegate to cloud agent'" - User delegates the task again.
5. "Go on. I dont know what you did and what failed, you need to tell me more" - User seeks clarification on previous actions and failures.]

[Technical Inventory: The conversation involves a repository named "frwg/mapbender" and a specific branch "develop-local." The user is working with a composer.json file located at "/home/frauch/Softwareentwicklung/mapbender-starter/application/composer.json."]

[Code Archaeology: The specific file being referenced is composer.json, but no modifications or code changes have been discussed in detail yet.]

[Progress Assessment: The user has not received any actionable proposals or insights from the cloud agent regarding the repository's structural issues. The user is seeking clarity on what actions were taken and what failed.]

[Context Validation: The user is focused on the "frwg/mapbender" repository and wants to ensure that any analysis or proposals are relevant to this specific context.]

[Recent Commands Analysis:

• Last Agent Commands:
  1. "Look at the repository in the cloud and make 10 proposals..."
  2. "Delegate to cloud agent"
  3. "Again. I am in the repo frwg/mapbender..."
  4. "Delegate: 'Delegate to cloud agent'"
  5. "Go on. I dont know what you did and what failed, you need to tell me more"
• Tool Results Summary: No specific results were returned from the cloud agent as the user canceled the initial request and sought clarification on subsequent actions.
• Pre-Summary State: The agent was actively trying to delegate the analysis task to a cloud agent when the token budget was exceeded.
• Operation Context: The user is focused on identifying structural issues in the "frwg/mapbender" repository and is frustrated by a lack of clarity on previous actions taken by the agent.]

1. Conversation Overview: - Primary Objectives: 1. "Look at the repository in the cloud and make 10 proposals where you detect structurally bad things that you think are worth to refactor." 2. "Go on. I dont know what you did and what failed, you need to tell me more." - Session Context: The user initially requested a structural analysis of a cloud repository, canceled that request, and clarified their focus on the "frwg/mapbender" repository. They expressed confusion about previous actions and sought more information. - User Intent Evolution: The user shifted from a broad request for analysis to a specific focus on a particular repository and branch, indicating a need for clarity and actionable insights.

2. Technical Foundation:

• Repository: "frwg/mapbender"
