feat(doom): Enhance telega clipboard and enable lisp

This commit introduces significant improvements to clipboard handling
within the Telega (Telegram) client and enables the LSP module.

### Telega Clipboard Enhancements
- Paste Images: Overrides the default image pasting
  function (`telega-chatbuf-attach-clipboard`) with more image format
  support.
- Copy Images: Adds a new interactive command,
  `+telega-save-file-to-clipboard`, to download a file from a message
  and copy it directly to the Wayland clipboard via `wl-copy`.

### LSP Support
- Enabled the `:tools lsp` module to activate Language Server Protocol
  support for improved code intelligence.
