fix: PDF export — tab chars garbled, unconditional bullets, encrypted PDF attachments

Browse source 
Root causes identified via DB hex-dump and server logs:

1. Tab character in budget lines: DB stores e.g. `**Budget Verantwortung:**\t750.000 EUR`
   (byte 0x09 between `:**` and the amount). PDFKit can't render \t in WinAnsiEncoding,
   producing garbage output like `"sSãUU`. Fix: `.replace(/\t/g, ' ')` in cleaned text.

2. Unconditional bullet: `\u2022 ${sanitize(hasBullet ? cleaned : cleaned)}` always
   prepended `•` — the ternary was a no-op. Fix: only add `•` when hasBullet is true;
   `**...**` header lines now render as Helvetica-Bold without a bullet.

3. ITIL4 Foundation Cert.pdf is owner-password-encrypted. pdf-lib threw
   "Input document is encrypted" → cert was silently skipped.
   Fix: `PdfLib.load(attBuffer, { ignoreEncryption: true })`.

Applies to both PDF and DOCX export paths.
