📌 Description

Prettifying notification HTML could crash the entire alert cycle when device free-text fields contained a bare <, causing all pending alerts to be retried and dropped again on the next run. This change escapes notification row string values before HTML table generation and makes final HTML rendering resilient to XMLTokenError.

  • HTML escaping in the notification path

    • Escapes string values in notification rows before passing them to json2table.
    • Keeps text/plain notification output unchanged.
  • Safer final HTML rendering

    • Escapes preheader entries before injecting them into the HTML template.
    • Wraps yattag.indent() and falls back to unindented HTML if pretty-printing fails.
  • Regression coverage

    • Adds focused tests for unescaped free-text content in notification HTML.
    • Adds explicit coverage for the pretty-print fallback path.
html_data = escape_html_rows(jsn)

try:
    return indent(mail_html, indentation="    ", newline="\r\n", indent_text=True)
except XMLTokenError:
    return mail_html

Merge Risk: 🔵 Low · up to 13da2

The change fixes notification HTML failures, but two new Portuguese labels are grammatically incorrect and could confuse users of the pt-BR interface. The PR is otherwise mergeable with explicit owner awareness or a small localization follow-up.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Correct the new pt-BR wording.

  • Use Cuidado. or Atenção. instead of Cuidadoso.. Cuidadoso is not a natural warning label.
  • Use Ainda não foi encontrado nenhum dispositivo for Device_NoData_Title. The current text has incorrect agreement with singular nenhum dispositivo.
Proposed wording
-    "Device_MultiEdit_Tooltip": "Cuidadoso. Clicar aqui aplicará o valor à esquerda a todos os dispositivos selecionados acima.",
+    "Device_MultiEdit_Tooltip": "Cuidado. Clicar aqui aplicará o valor à esquerda a todos os dispositivos selecionados acima.",
...
-    "Device_NoData_Title": "Ainda não foram encontrados nenhum dispositivo",
+    "Device_NoData_Title": "Ainda não foi encontrado nenhum dispositivo",
