feat: improve notification format and add proxy/timezone support

- Add emoji tags for event types (PUSH, RELEASE, ISSUE, PR)
- Strip markdown formatting from issue/PR body for cleaner display
- Add proxy support for Telegram API (HTTP/SOCKS5)
- Add timezone configuration for notification timestamps
- Add /test command to preview all notification formats
- Add inline keyboard buttons for subscription management
- Fix unchecked error returns (lint errors)
