Prepare v1.76.0-beta.1

Prepare the first beta after stable v1.75.0 from the exact integrated dev
tree. Version sources, bilingual changelogs, release notes, status and both
committed bundle snapshots move together.

Pinned local proof: Node 22.23.2 and Python 3.14.7; npm test 2618 passed,
0 failed, 1 skipped; production bundle sync and budget passed; config reload,
pan coverage, post-write adoption and summary-panel browser smokes passed;
targeted pure backend 197 passed. Bundle headroom is 12,830 B, below the
warning threshold but inside the enforced ceiling.

 ## Основное
 
-- Пункт меню House Plan больше не застревает на прошлой версии карточки: он тянул её по единственному адресу без версии, и браузер был вправе часами отдавать копию из кэша ([#535](https://github.com/Matysh/houseplan-card/issues/535)).
+- План больше не откатывается к старой версии из-за запоздавшей загрузки подложки и не показывает пустую полосу у входящего края при перетаскивании и масштабировании ([#543](https://github.com/Matysh/houseplan-card/issues/543), [#544](https://github.com/Matysh/houseplan-card/issues/544)).
+- Настройки видимости и размера сводной панели больше не переходят между карточками House Plan после полной перезагрузки Masonry ([#561](https://github.com/Matysh/houseplan-card/issues/561)).
 - Мелкие исправления и улучшения.
 
 ## Highlights
 
-- The House Plan sidebar page no longer gets stuck on a previous version of the card: it fetched the card through the one address that carries no version, and a browser was free to serve a cached copy for hours ([#535](https://github.com/Matysh/houseplan-card/issues/535)).
+- The plan no longer rolls back to an older version because a background image loaded late, and dragging or pinching no longer reveals a blank strip along the incoming edge ([#543](https://github.com/Matysh/houseplan-card/issues/543), [#544](https://github.com/Matysh/houseplan-card/issues/544)).
+- Summary-panel visibility and size preferences no longer move between House Plan cards after a full Masonry reload ([#561](https://github.com/Matysh/houseplan-card/issues/561)).
 - Small fixes and improvements.
