feat(server): structured logging

[seriousben]

Context

To help operationalize indexify-server, it needs to output structured logs.

What

indexify-server now defaults to structured logging unless it is started with the new --dev flag.

> ./indexify-server -h

Usage: indexify-server [OPTIONS]

Options:
  -d, --dev                   Development mode
  -c, --config <config file>  Path to config file
  -h, --help                  Print help
  -V, --version               Print version

> RUST_LOG=debug ./indexify-server  --dev

> RUST_LOG=debug ./indexify-server
