feat: prompt sections + memory route via CRM; legacy Notes migration

Three changes paired with SmartAssistant 2.10.0:

1. prompt_builder.py — every prompt section (tool_rules, writing_style,
   legal_assistance, personality_case, personality_office, other_rules_case,
   other_rules_office) now reads from context['assistantPrompts'][key]
   with the existing string as a fallback default. Admins editing
   AssistantPrompt rows in the EspoCRM UI immediately affect the next
   conversation. A missing/inactive row falls back to the in-code default
   so deleting everything in the UI never bricks Shira.

   Also: the user-profile section now prefers context['userProfile']
   (from the new UserProfile entity) over the explicit `user_profile`
   parameter, completing the move from /opt/data/profiles/*.md to the CRM.

2. crm_tools.py:save_memory — stops POSTing directly to /Note with a
   '🧠 category:' prefix. Routes through SmartAssistant/action/executeTool
   so the PHP saveMemory handler actually creates a CaseMemory row.
   Cause of yesterday's prod issue: CaseMemory table was empty even
   though Shira was "saving" to it.

3. scripts/migrate_legacy_memory_notes.py — one-shot migration that
   sweeps all existing '🧠 category: ...' Notes into CaseMemory rows
   and soft-deletes the originals. Idempotent; safe to re-run.
