This pull request makes several improvements and refactors across the repository crate, focusing on type consistency, code readability, and maintainability. The most significant changes include standardizing integer types for server-related timestamps and values, reorganizing module imports for clarity, and reformatting code for better readability. Additionally, there are minor dependency updates and some bugfixes related to type usage.

Type consistency and bugfixes:

• Changed various struct fields and function signatures from u32 to i32 for last_connected, RecordData, and related values to ensure consistency with database types and prevent potential bugs. (backend/crates/repository/src/models/record.rs [1] [2]; backend/crates/repository/src/models/server.rs [3] [4]; backend/crates/repository/src/postgres.rs [5] [6]
• Updated function signatures and internal logic in the repository implementation to use i32 where appropriate for ping and server values. (backend/crates/repository/src/postgres.rs [1] [2]

Code organization and readability:

• Reorganized module imports and declarations for clarity and consistency, especially in lib.rs, mod.rs, and postgres.rs. (backend/crates/repository/src/lib.rs [1]; backend/crates/repository/src/models/mod.rs [2]; backend/crates/repository/src/postgres.rs [3]
• Reformatted and expanded multi-line function calls, conditionals, and queries to improve code readability and maintainability throughout the duplicate detection and repository modules. (backend/crates/repository/src/duplicate_detection.rs [1] [2] [3] [4] [5]; backend/crates/repository/src/postgres.rs [6] [7] [8] [9] [10] [11] [12] [13]

Dependency and enum improvements:

• Updated the minecraft-pinger dependency from 0.1.8 to 0.1.10. (backend/Cargo.toml backend/Cargo.tomlL7-R7)
• Added missing trailing commas in enums for style consistency. (backend/crates/repository/src/models/server.rs backend/crates/repository/src/models/server.rsL125-R127)
• Fixed a missing trailing comma in the RepositoryError enum. (backend/crates/repository/src/error.rs backend/crates/repository/src/error.rsL11-R11)

Import and ordering fixes:

• Sorted and grouped imports for consistency and to resolve potential issues with import order. (backend/crates/repository/src/duplicate_detection.rs backend/crates/repository/src/duplicate_detection.rsL1-R9)

These changes collectively improve the maintainability, correctness, and style consistency of the codebase.
