Squash migrations

[j-chmielewski]

• Squashes all 2.0.0 migrations into one
• Adds supplementary DB indices
• Adds gateway-config command that prints gateway configuration

[Copilot]

Pull request overview

This PR consolidates a set of 2.0.0-era database migrations into a single “squashed” migration, and refactors gateway configuration generation by centralizing the Configuration mapping in defguard_proto and exposing a CLI subcommand to print a location’s gateway config.

Changes:

• Squash multiple 2.0.0 migrations into 20251218140442_[2.0.0]_initial.(up|down).sql and remove the previously separate migration files.
• Add defguard_proto::gateway::Configuration::new(...) and update gateway manager code/tests to use it instead of a local helper.
• Add Command::GatewayConfig plus defguard_core::gateway_config(...) to output the gateway gRPC configuration for a location.
