Add connection URL output when creating or resetting Postgres roles

[SimeonGriggs]

Summary

• Display credentials in a vertical layout when creating a role or resetting a role's password
• Add DATABASE URL field with a ready-to-use PostgreSQL connection string
• Makes it easier for users to copy credentials without having to construct the URL manually

Changes

Updates three commands:

• pscale role create
• pscale role reset
• pscale role reset-default

Example Output

Role my-role was successfully created in mydb/main.
Please save the values below as they will not be shown again

ID                 role-abc123
NAME               my-role
USERNAME           my-role_abc123
PASSWORD           secretpass123
ACCESS HOST URL    pg.psdb.cloud
DATABASE URL       postgresql://my-role_abc123:[email protected]:5432/postgres?sslmode=verify-full

Notes

• JSON/CSV output includes the new database_url field
• Uses sslmode=verify-full for maximum security
• URL-encodes username and password to handle special characters
• Defaults to port 5432 if not specified in the access host URL
