Move charts to standard Helm structure with charts directory

This reorganizes the chart structure as requested in issue opencloud-eu#6:
- Move main chart to /charts/opencloud
- Move dev chart to /charts/opencloud-dev
- Update README paths
- Set gateway.create to false as requested

This follows standard Helm chart repository organization and
makes the repository compatible with chart-testing.
