Make Atheme hub server configurable for failover scenarios
e64df58 
Add environment variables ATHEME_HUB_SERVER and ATHEME_HUB_HOSTNAME
to enable dynamic hub server configuration for Atheme services.

## Changes Made

- **atheme.conf.template**: Use ${ATHEME_HUB_SERVER} and ${ATHEME_HUB_HOSTNAME}
  variables instead of hardcoded magnet-9RL values
- **start-atheme.sh**: Add new variables to envsubst template processing
- **fly.toml**: Set default values for hub configuration variables
- **Documentation**: Update container architecture and admin procedures
  with hub failover instructions
- **Tests**: Update Docker build tests to validate configurable hub variables

## Benefits

- **Operational Flexibility**: Easy hub server changes via environment variables
- **Failover Support**: Quick switching to backup hub servers during maintenance
- **Development Testing**: Simplified testing with different hub configurations
- **Zero Downtime**: Hub changes without code modifications

## Usage

```bash
# Switch to backup hub server
fly secrets set ATHEME_HUB_SERVER=magnet-1EU --app magnet-atheme
fly secrets set ATHEME_HUB_HOSTNAME=magnet-1eu --app magnet-atheme
fly machines restart --app magnet-atheme
```

Remove unnecessary Tailscale cleanup script
ddde765 
Ephemeral devices clean themselves up automatically when containers stop.
Manual cleanup scripts go against the principle of ephemeral devices and
are not needed.

## Changes Made

- **Removed scripts/cleanup-tailscale.pl**: Unnecessary for ephemeral devices
- **Updated tests**: Focus on ephemeral device lifecycle validation
- **Updated documentation**: Emphasize automatic cleanup behavior
- **Simplified architecture**: Rely on Tailscale's built-in ephemeral cleanup

## Benefits

- **Simpler architecture**: Fewer scripts to maintain
- **True ephemeral behavior**: Let Tailscale handle device lifecycle
- **Reduced complexity**: No manual intervention needed
- **Better alignment**: Follows Tailscale ephemeral device design

Ephemeral devices automatically disappear when containers stop - that's
exactly what we want for container-based infrastructure.

Clarify GitHub repository secrets for CI/CD deployment
290c2de 
Both TAILSCALE_AUTHKEY and FLY_API_TOKEN are GitHub repository secrets,
not Fly.io secrets. The GitHub Actions workflow handles setting these
as Fly.io secrets during deployment.

## Changes Made

- **GitHub Actions workflow**: Add TAILSCALE_AUTHKEY environment variable
- **Deployment step**: Automatically set Tailscale auth key in Fly.io secrets
- **Documentation**: Clarify both secrets are GitHub repository secrets
- **Admin procedures**: Update key rotation to use GitHub secrets first
- **Deployment prerequisites**: Document both required GitHub secrets

## Required GitHub Repository Secrets

1. **FLY_API_TOKEN**: Fly.io deploy token for automated deployment
2. **TAILSCALE_AUTHKEY**: Ephemeral auth key for Tailscale mesh access

## GitHub Actions Workflow

The workflow now:
- Uses both secrets from GitHub repository settings
- Automatically sets TAILSCALE_AUTHKEY as Fly.io secret for each app
- Maintains existing FLY_API_TOKEN usage for deployment authentication

This provides proper separation between GitHub CI/CD secrets and
runtime Fly.io application secrets.
