Version 1.3.3 build 3fadd86

Checkouts and reminder workflow

• Added manual return reminders for overdue checkouts, including a direct Notify action for active overdue loans, cooldown handling, reminder timestamps, and clearer status feedback in the checkout list.
• Improved checkout reminder mails so they respect the configured installation language instead of always sending mixed bilingual text, and documented the shared mail locale behavior through configuration.
• Refined overdue checkout presentation across item details and operations screens so overdue states stand out more clearly and reminder actions fit the existing item+ button language better.

Maintenance and stock workflow

• Moved item-specific maintenance handling into dedicated per-item maintenance pages instead of keeping reminder management embedded inside the item detail view, keeping item details calmer while giving maintenance its own focused workspace.
• Added completion-note handling to maintenance history and improved how notes and status history are shown for finished reminders.
• Tightened stock movement and stock-detail navigation so operational views link to the stock perspective where it makes more sense than jumping back to the generic item detail page.
• Clarified stock movement semantics for checkout-related events by treating loan and return entries as availability changes instead of fake quantity mutations in the global stock count.

Navigation and embedded web app stability

• Fixed sidebar behavior so favorites stay open when a page was entered through favorites, while inventory, operations, system, and settings stay open when the same target was opened through their normal section.
• Extended that navigation memory across the whole app instead of only solving it for one page, making the sidebar feel more intentional during deeper navigation.
• Fixed long-running embedded web app setups by extracting the internal Next.js build into a persistent runtime directory instead of macOS/Linux temp storage, which could be cleaned up after days of uptime.
• Routed embedded web app output back into the normal item+ logging stream so future runtime issues can be diagnosed without blind spots.

UI polish and master data

• Improved master-data logo handling with larger list previews and continued cleanup around vendor logo resolution behavior.
• Refined item detail action shortcuts and operational links so maintenance and stock actions are easier to reach directly from the item context.
• Added and refreshed support-page content in the public docs to better match the current product and review/support expectations.
