Optimize logger by creating single pino instance at module scope

[Copilot]

The logger was creating a new pino instance on every log call (buildBaseLogger() invoked in each function), causing unnecessary memory allocation and instantiation overhead.

Changes

• Replace buildBaseLogger() function with module-scoped logger constant
• Update all logging functions (loggyInfo, loggyDebug, loggyWarn, loggyTrace, loggyFatal, loggyError) to reference shared instance
• Fix typo: "Recieved" → "Received" in loggyRequestReceived

Before:

const buildBaseLogger = () => {
  return pino({ /* config */ })
}

export const loggyInfo = (...) => {
  buildBaseLogger().info({ ... })  // New instance every call
}

After:

const logger = pino({ /* config */ })

export const loggyInfo = (...) => {
  logger.info({ ... })  // Reuse shared instance
}
