No support for multiple `--scale` flags

[Naapple]

Describe the bug
When doing

podman-compose up --scale x=2 --scale y=3

podman-compose ignores the first --scale and only parses the final --scale flag, correctly scaling y to 3, but x to whatever is defined in the compose.yml

To Reproduce
Steps to reproduce the behavior:

1. Content: Simple docker-compose.yml with two services in current working directory:

services:
    client:
        image: alpine:3.23.5
        command: ["sleep", "infinity"]
        deploy:
            mode: replicated
            replicas: 1

    bootstrap:
        image: alpine:3.23.5
        command: ["sleep", "infinity"]
        deploy:
            mode: replicated
            replicas: 1

2. podman-compose up -d --scale client=3 --scale bootstrap=4

Expected behavior
Both --scale flags are parsed and client deploys with 3 replicas, and bootstrap 4 replicas.

Actual behavior
Only the final --scale flag is parsed, and client deploys with 1 replica, and bootstrap 4 replicas.

Output

$ podman-compose --version
podman-compose version 1.6.0
podman version 5.5.1

$ podman-compose up -d --scale client=3 --scale bootstrap=4

Additional Notes
Unrelated, I also noticed in the compose.yml, deploy requires mode: replicated in order to acknowledge the replicas set in the compose.yml. Else the number of replicas set is one. Is this intended? I noticed older versions of podman-compose didn't have this limitation (e.g., v1.0.6). If it's not intended behavior, I can create another issue to address that, as well.
