When ENABLE_LOGO_MODE is on, messages are sent as photos which
naturally don't show URL previews. When off, messages are sent as
text but disable_web_page_preview was never set, causing link
previews in menu, welcome, and other messages.
Always patch Message.answer/edit_text and inject
disable_web_page_preview=True for all text message paths.
After first logo upload, Telegram returns a file_id that can be reused
for all subsequent sends. This eliminates 3-4 second delay per message
caused by re-uploading the same file from disk every time.
