fix(chat): avoid full secret exposure for 7-char secrets (#1942)

- ensure at least 40% of the characters are masked for secrets of length 4 or more
- secrets with length <= 6 now show first and last char with mask
- secrets with length <= 12 now show first two and last two chars
- longer secrets show 3 prefix and 4 suffix
