feat(text): add text analysis pipeline & surface results in UI

- engine: add analyse_text() to extract visible page text and evaluate
  category="text" rules; collect matched phrases and expose as
  `content_snippet` (deduped, length-capped via settings.ui.snippet_preview_len).
- engine: removed unused code
- browser: removed double call for enrichment
- engine: improve regex compilation — honor per-rule flags (string or list)
  and default IGNORECASE when category=="text".
- engine: add dispatch logging "[engine] applying categories: …" gated by
  settings.app.print_rule_dispatch.
- ui(templates): add `templates/partials/result_text.html` mirroring the forms
  table; renders page-level records and their matched rules.
- ui(controller): wire `analyse_text()` into scan path and expose
  `payload["suspicious_text"]`.
- rules(text): add `identity_verification_prompt`, `gated_document_access`,
  `email_collection_prompt`; broaden `credential_reset`.

fix: text indicators were not displayed due to missing analyzer and mismatched result shape.

Result shape:
  suspicious_text: [
    {
      "type": "page",
      "content_snippet": "...matched phrases…",
      "rules": [
        {"name": "...", "description": "...", "severity": "medium", "tags": ["..."]}
      ]
    }
  ]
