change to metro routing

[juan-malbeclabs]

This pull request standardizes the naming of a configuration field across the codebase by renaming all instances of metro_route to metro_routing. This change affects the smart contract state, CLI commands, SDK, test cases, and documentation to ensure consistency and clarity.

Field renaming for consistency:

• Renamed the metro_route field to metro_routing in the Tenant struct and all related smart contract logic, including serialization/deserialization, display, and validation (smartcontract/programs/doublezero-serviceability/src/state/tenant.rs, smartcontract/programs/doublezero-serviceability/src/processors/tenant/create.rs, smartcontract/programs/doublezero-serviceability/src/processors/tenant/update.rs) [1] [2] [3] [4] [5].

• Updated CLI command argument and struct field names from metro_route to metro_routing in CreateTenantCliCommand, UpdateTenantCliCommand, and related display and list logic (smartcontract/cli/src/tenant/create.rs, smartcontract/cli/src/tenant/update.rs, smartcontract/cli/src/tenant/list.rs, smartcontract/cli/src/tenant/get.rs) [1] [2] [3] [4] [5] [6] [7].

• Modified all related test cases and test data to use the new metro_routing field name instead of metro_route across the CLI, SDK, and smart contract test files (smartcontract/cli/src/user/get.rs, smartcontract/cli/src/user/list.rs, client/doublezero/src/command/connect.rs, smartcontract/programs/doublezero-serviceability/src/instructions.rs, smartcontract/programs/doublezero-serviceability/tests/accesspass_test.rs, smartcontract/programs/doublezero-serviceability/src/state/tenant.rs) [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] [15] [16].

Documentation and changelog updates:

• Updated all references to metro_route to metro_routing in the CHANGELOG.md and SDK documentation to reflect the new field name and maintain accurate documentation (CHANGELOG.md) [1] [2].
