Stop asking for Russian in English on the last three prompts (V-404)

#400 rewrote the chat and query prompts in Russian and left three pieces
of English prose behind.

PhraseReminder's user prompt was fully English. It is Russian now, and it
no longer restates the JSON contract or the persona rules: the call goes
through chat(), so nudgeSystem already states both, and a second copy of a
contract is one more thing that can drift out of step with the first.

querySystemPrompt and router.KnowledgePrompt both closed with the English
"Respond ONLY with valid JSON:". That sentence is prose instruction, not
wire format — the JSON skeleton after it is the wire format, and it is
unchanged. Kept rather than deleted: the GBNF grammar makes it close to
redundant, but the grammar is switchable off (phraser NoGrammar), and the
sentence is the floor when it is.
