<issue_title>PHPStan Error Analysis: 6349 Errors - Systematic Resolution Plan</issue_title>
<issue_description># PHPStan Error Analysis Report

Executive Summary

The PHPStan analysis of the codebase revealed a total of 6349 file errors. While this number appears high, a significant portion of these errors are related to missing type information and dynamic property access, which can be systematically addressed. There are also critical issues related to nullability and incorrect data types that pose a direct threat to the operational stability of the application. The new "enterprise transformation" features appear to contribute to these errors, indicating a need for more rigorous static analysis and typing within these modules.

Error Categorization and Impact

The errors can be broadly categorized as follows:

1. Missing Type Information (High Count, Medium Severity)

Examples:

• Method App\Actions\Application\GenerateConfig::handle() has no return type specified. (Numerous occurrences, 574/574 files have errors related to this)
• Unable to resolve the template type TValue in call to function collect (93 occurrences)
• Property App\Livewire\Project\Application\General::$parsedServices with generic class Illuminate\Support\Collection does not specify its types: TKey, TValue (Numerous occurrences)

Analysis: This category represents a large portion of the errors. While PHP itself might run without explicit type declarations, static analysis tools like PHPStan rely heavily on them for accurate checks. The lack of return type declarations, generic type specifications for collections, and un-typed properties lead to PHPStan being unable to fully verify code correctness.

Operational Impact:

• Maintainability: Lowers code readability and makes it harder for developers to understand expected data types, increasing the risk of introducing bugs.
• Reliability: Can lead to unexpected runtime type errors if incorrect data is passed, especially when refactoring or extending functionality.
• Developer Experience: PHPStan provides less value in catching bugs early, requiring more manual testing.

2. Access to Undefined Properties (High Count, High Severity)

Examples:

• Access to an undefined property App\Models\Server::$settings. (175 occurrences)
• Access to an undefined property App\Models\Application::$settings. (143 occurrences)
• Access to an undefined property App\Models\Organization::$activeLicense. (28 occurrences)

Analysis: This is a critical category. It often arises when Eloquent models dynamically provide properties (e.g., through relationships) that are not explicitly declared in the class. Without @property annotations or explicit property declarations, PHPStan cannot confirm their existence, leading to errors. This can also indicate actual typos or incorrect property access.

Operational Impact:

• Runtime Errors: If the property genuinely does not exist or the relationship is not loaded, accessing it can lead to fatal "Undefined property" errors, crashing the application.
• Debugging Difficulty: Such errors can be hard to debug as they might only manifest under specific conditions.
• Code Fragility: Code becomes brittle as changes to underlying relationships or model structure can easily break existing logic.

3. Nullability Issues (Medium Count, High Severity)

Examples:

• Cannot call method currentTeam() on App\Models\User|null. (66 occurrences)
• Parameter johnproblems/topgun#1 $json of function json_decode expects string, string|null given. (47 occurrences)
• Cannot access property $server on Illuminate\Database\Eloquent\Model|null. (13 occurrences)

Analysis: These errors occur when methods are called or operations are performed on variables that might be null, but the context expects a non-null value. This is a common source of TypeError or "Call to a member function on null" runtime exceptions.

Operational Impact:

• Application Crashes: Directly leads to fatal errors and application downtime if not handled correctly.
• Data Corruption: Can result in incorrect data processing or storage if null values are not properly validated before use.
• Security Vulnerabilities: In some cases, unexpected null values can bypass validation logic, leading to security risks.

4. Incorrect Type Usage / Type Mismatches (Medium Count, Medium Severity)

Examples:

• Parameter $properties of class OpenApi\Attributes\Schema constructor expects array<OpenApi\Attributes\Property>|null, array<string, array<string, string>> given. (66 occurrences)
• Parameter johnproblems/topgun#1 $string of function trim expects string, string|null given. (16 occurrences)
• Property App\Models\Server::$port (int) does not accept string. (1 occurrence)

Analysis: These indicate that a function or method is being called with arguments ...
