fix: migrate email template to Odoo 17 syntax; fix BDD LLM mock JSON

PRODUCTION BUG: email template used pre-Odoo-14 Mako syntax (${} and
% for/% if), which Odoo 17 does not render — real notification emails
would show literal '${object.blog_post_id.name}' in the subject.
- subject/email_from: ${...} → {{ ... }} (inline_template engine)
- body_html: add type="qweb"; ${x} → <t t-out="x"/>;
  % for → <t t-foreach t-as>; % if → <t t-if>

BDD: when_llm_router_called mocked provider.generate() returning raw
HTML in .text, but LLMRouter._parse_response expects JSON and raised
UserError before ctx['mock_generate'] was set. Now returns valid JSON
with all required fields, and records the mock before generate() runs.
