EventLogExpert: allar útgáfur og eldri útgáfur

All changes since the last stable release (v26.8.24.986).
Highlights
- Notifications move into a status-bar notification center — notification banners used to span the top of the window and could cover the filter toolbar, so new users didn't realize the filter menu was hiding behind them (#751). Ordinary notifications now live behind a notification button on the status bar that opens a popover listing every active notification as a card with its usual actions, with a brief toast when a new one arrives and a confirmed Clear all. Only critical errors keep the full-width banner, and dialogs get their own notification button in their header. See Notification Center below.
- Date filters that stay put, plus a fix for swapped Exclude Events Before / After — the Exclude Events Before and Exclude Events After context-menu actions were swapped and now do what they say, both only ever narrow an enabled date filter, and the date filter keeps its wall-clock values when the display time zone changes (After 09:00 stays 09:00). The date editor also gained open-ended bounds, new quick ranges, clearer validation, and a visible time zone. See Date Filtering below.
- Sort and group the event table from anywhere, with clear active-state cues — columns can now be sorted and grouped from the column-header menu, the cell right-click menu, the group-header menu, and a new View → Group By picker, and the active ordering is surfaced as status-bar chips (with direction toggles and clear buttons), column-header indicators (a sort caret and a grouped-column chevron), and screen-reader announcements. The table stays coherent while a reprojection is updating or has faulted, and you can now keep grouping by a column you've hidden. See Sorting & Grouping below.
- Neutral default theme, with the blue design kept as opt-in Modern themes — the default Light / Dark / System themes now use a clean, neutral Windows Event Viewer / MMC-style palette (neutral gray chrome, black/gray body text, and theme-tuned blue bars and selection), which is lower cognitive load for long sessions over a dense grid and matches what you expect coming from Event Viewer. The app's original blue-accent design is preserved as two new opt-in themes, Modern Light and Modern Dark. See Themes below.
- Accessible tooltips on keyboard focus and hover — the app's native title tooltips were replaced with a custom tooltip that appears on keyboard focus as well as hover, renders above modal dialogs, is dismissable with Escape, and has native-feeling cursor-anchored timing. Icon-only buttons across the filter pane, log tabs, details pane, Database Tools, and more now surface a visible label, and clipped combobox options reveal their full text when you arrow to them. See Tooltips below.
- Disabled controls now explain themselves — a control that's disabled for a non-obvious reason now shows a short "why + how to enable" tooltip (for example, a Database Tools Run button names the first unmet prerequisite), exposed to screen readers as well. See Tooltips below.
- Broad accessibility pass — a sweep against a formal accessibility review fixed color-contrast throughout (every foreground/background pair clears WCAG AA in all five themes), added keyboard-only focus rings and F6 / Shift+F6 pane navigation, corrected keyboard behavior for menus and comboboxes, fixed High Contrast (forced-colors) rendering, and made toolbars, panes, and modals reflow cleanly at 200% text zoom and 320px width. See Accessibility below.
- App-wide localization and regional formatting — the entire UI now routes its text through the localization system, so EventLogExpert can follow your Windows display language (including right-to-left layout) with no in-app language setting, and display numbers, sizes, and dates now follow your regional format while identifiers and persisted values stay invariant. English is byte-for-byte unchanged; translations will light up as they're added. See Localization below.
- Dependency and security refr
