Create a new modelardb_test crate for test functionality

[CGodiksen]

This PR implements #260 by creating a new modelardb_test crate for shared test functionality. modelardb_common has also been removed since most of the code that was left in modelardb_common after recent changes was test util.

Note that some functionality was duplicated when moved out of modelardb_common and into modelardb_manager and modelardb_server. This is not considered a problem since modelardb_manager will be removed.

Pull Request Overview

This PR implements issue #260 by replacing the deprecated modelardb_common crate with a new modelardb_test crate for shared testing utilities, updating imports and dependencies across all crates, and adding local command-line argument helpers in the server and manager binaries.

• Created modelardb_test crate and moved test constants/functions into it
• Removed modelardb_common references and updated imports throughout the workspace
• Added collect_command_line_arguments and print_usage_and_exit_with_error in server and manager binaries

• [nitpick] Public helper functions should have doc comments explaining their behavior and parameters for improved maintainability.

pub fn print_usage_and_exit_with_error(parameters: &str) -> ! {

crates/modelardb_server/src/remote.rs:240

• [nitpick] Returning &String may be less ergonomic than &str; consider returning &str to simplify the API for callers.

pub fn table_name_from_flight_descriptor(

crates/modelardb_storage/src/metadata/table_metadata_manager.rs:544

• [nitpick] Consider using the ERROR_BOUND_ZERO constant from modelardb_test instead of the literal 0.0 to avoid a magic number and maintain consistency.

            vec![ErrorBound::try_new_absolute(0.0)?; query_schema_columns];

crates/modelardb_server/src/main.rs:114

• [nitpick] This function is duplicated in modelardb_manager; consider extracting argument parsing utilities into a shared module or crate to reduce duplication.

pub fn collect_command_line_arguments(maximum_arguments: usize) -> Vec<String> {

crates/modelardb_server/src/remote.rs:258

• [nitpick] The error_to_status_* helpers are duplicated in modelardb_manager; extracting them to a shared utility module would reduce code duplication.

pub fn error_to_status_invalid_argument(error: impl Error) -> Status {
