fix(outages): do not space-pad ordinals in the portal LIKE pattern

likePattern padded every token containing a digit, including ordinals like
"3-я". When the ordinal starts the address, " 3-я " never matches, so
"3-я Механическая улица 24а" returned no outages. Pad only pure-numeric
house tokens; precision is enforced by the local house filter regardless.
