This adds a `format` query parameter to workspace build logs, workspace
agent logs, template version logs, and template version dry-run logs
endpoints. When `format=text` is specified, logs are returned as plain
text with RFC3339 timestamps instead of JSON.

Each log line is formatted as:
- Provisioner logs: `{timestamp} [{level}] [{source}] {stage}: {output}`
- Agent logs: `{timestamp} [{level}] {output}`

ANSI escape sequences in log output are preserved.

The UI now includes "View raw logs" links:
- Workspace build page (build logs and agent logs tabs)
- Template version editor (output tab)
- Template version page (stats bar)
