向前兼容memos到v0.18

Introduce compatibility layers and runtime detection for older Memos API variants (v0.18/v0.19/v0.20/v0.21/v0.23 and older). Added js/compat/memosApi.v023.js and js/compat/memosApi.v1.js to provide filter building, listing, upload and resource helpers for legacy endpoints. Updated js/oper.js to track apiFlavor, probe/detect flavor on save, and to adapt uploads, deletes, tag listing, search and preview image hydration to the appropriate API flavor (including buildV1ResourceStreamUrl, normalizeUnixTimeToMs, getMemoUid and other helpers). Also updated user-facing strings and README to reflect broader compatibility (locales and README changes) and minor UI/manifest popup adjustments. These changes enable the extension to work with a wider range of Memos server versions while preserving existing behavior for modern endpoints.
