Version 1.6.4

Receipts: PDF download

• The receipt print page now shows a “Download PDF” button alongside the existing print action when available.Added PDF download for receipts using server-side generation
• Added unit tests for receipt print and download flows (authenticated and public token-based), plus coverage for ReceiptTokenService methods.

Projects: implementing partner is now optional

• Made Implementing Partner optional on projects (model + form), removing the mandatory constraint and the hardcoded required asterisk in the UI.
• Fixed the public subsite Funding Projects injection code to safely handle projects with no partner (avoids AttributeError).
• Enhanced the funding-projects modal to show Program Center details (name, location, address, sector, about) when present; omitted when not set.

Image Vault: protect system albums from editing

• The Image Vault is a protected system album and should not be modifiable by users.
• Hidden edit/delete actions for protected vault albums and their photos/videos across the gallery list, album detail, and photo view screens.

Public Subsite: FAQ accordion fix + theme-aligned UI

• Fixed the subsite FAQ accordion breaking after save by allowing <button> tags through HTML sanitisation.
• Added a repair routine to rebuild missing accordion buttons from already-stored broken page content (no resave required).
• Applied theme colours to accordion UI states (active colour/background, focus ring, expanded chevron) so all themes render correctly.
• Improved spacing consistency by removing redundant inner py-5 padding in injected live sections.
• Added hero / hero-image section styles to components.css so these sections render correctly both on the public page and inside the editor preview.

Production fix: document viewer & downloads no longer fail with GCS AccessDenied

• Fixed a production issue where the document viewer iframe (and downloads) could fail with anonymous GCS AccessDenied errors.
