[APIP + AIWS] Enhance logging and configuration in platform API

[Thushani-Jayasekera]

#2345

• Integrated a custom logger into the configuration loading process to ensure consistent log formatting across the application.
• Updated the configuration file to enable SQLite database by default.
• Improved source file path handling in the logger for better clarity in log messages.
• Changed log output format for server startup to provide clearer information on the running mode.

📝 Walkthrough

Walkthrough

This PR installs the configured logger as the process-wide slog default in platform-api's config loading, replaces server startup banner logic in both the Platform API server and the AI Workspace BFF with structured slog logging plus a shared printStartedMarker console banner, and activates SQLite database settings in config.toml.

Changes

Logging Setup and Startup Output

Layer / File(s)	Summary
Default slog logger wiring platform-api/config/config.go	Imports the internal logger package and installs a configured slog default logger using cfg.LogLevel and cfg.LogFormat during LoadConfig.
Platform API server startup output platform-api/internal/server/server.go	Replaces centered fmt.Printf banner with uppercase PRODUCTION/DEMO mode selection, a structured slog.Info("Platform API started") call, and a new printStartedMarker helper for console output.
AI Workspace BFF startup output portals/ai-workspace/bff/main.go	Replaces the old banner helper with printStartedMarker, computes mode from cfg.DemoMode, adds mode to the structured startup log, and calls the new banner function.

Database Configuration

Layer / File(s)	Summary
SQLite config activation platform-api/config/config.toml	Enables driver = "sqlite3" and sets path to /app/data/api_platform.db under [database], replacing previous commented defaults.

Poem:
A rabbit hopped through logs at dawn,
Set slog's default before code's spawn.
Banners bloomed with PRODUCTION flair,
SQLite paths now active there.
Hop, hop, deploy — the marker's shown! 🐇

In `@platform-api/src/internal/server/server.go`:
- Around line 807-812: The Platform API startup log is using the wrong slog
attribute key, with `server.go`’s startup message in the `Info` call passing
`"mode="` instead of `"mode"`. Update the `s.logger.Info("Platform API started",
...)` call in `server.go` to use the standard key/value pair format with the
`mode` key so the log renders correctly in both text and JSON output.
