chore(deps)!: update tls deps, remove built-in tls server support (#3091)

Update reqwest from 0.12 to 0.13 and remove the built-in TLS termination
from atuin-server. Users should use a reverse proxy (nginx, caddy,
traefik) for TLS/HTTPS support instead.

This removes:
- axum-server and rustls dependencies
- The [tls] configuration section
- The launch_with_tls function

Also updates metrics-exporter-prometheus from 0.17 to 0.18.

The reverse proxy approach is standard and provides better flexibility
for certificate management. I'd rather keep our server stack as minimal
as possible.

 ### TLS
 
-The server supports TLS through the `[tls]` section:
+For TLS/HTTPS support, we recommend using a reverse proxy such as nginx, caddy, or traefik in front of the Atuin server. This is the standard approach for containerized applications and provides better flexibility for certificate management.
 
-```toml
-[tls]
-enable = true
-cert_path = "/path/to/letsencrypt/live/fully.qualified.domain/fullchain.pem"
-pkey_path = "/path/to/letsencrypt/live/fully.qualified.domain/privkey.pem"
-```
+> **Note:** The built-in `[tls]` configuration option has been removed. If you were previously using it, please migrate to a reverse proxy setup. Any existing `[tls]` sections in your config will be ignored.
