Long resp handling

[MrOrz]

Fixes #395

• Implements a new reply token management mechanism to handle long-running queries.
• Adds utility function setReplyTokenCollectorMessage(ctx: Context, message: string) to tell the user about current progress on timeout
  • Ensures that before the 1-minute timeout, the bot sends a message with a quick reply to collect a new reply token.
• Modifies singleUserHandler to remove the isRepliedDueToTimeout flag.
• Updates the send() function to consume the reply token if it hasn't timed out or use a push message if the token has expired.

Updates on tests

• For handlers that calls displayLoadingAnimation, mock lineClient to suppress the warning caused by sending request with invalid token to LINE server.
• setReplyToken() timeout mechanism is tested in src/webhook/handlers/__tests__/utils.test.js
• For handlers that imports webhook/handlers/utils directly or indirectly:
  • handler implementations usually imports from webhook/handlers/utils; we add redis.quit() in setup-jest to stop the Redis connection to avoid open handles caused by Redis connection.
  • If a test file mocks other handlers, implement the mock with jest.fn() so that we don't accidentally create connections to Redis in the namespace for mocks
    • It seems that the redis client instance in mock namespace and test files (setup-jest) are separate, so redis.quit() in setup-jest does not break the connection when redis client is instantiated under mocks.

Other refactors

• Prepend [...] to logging to identify where a certain error message is from
