MM-70493: Let the pages sidebar widen, and reach the page menu with Tab#41calebroseland wants to merge 4 commits into

MAX_SIDEBAR_WIDTH equalled DEFAULT_SIDEBAR_WIDTH (232), so the pages sidebar could only be dragged narrower, never wider, and page names in the tree truncated at a width the user had no way to increase. Raise the cap to 400 and clamp the rendered width to 40% of the window on top of it, so a sidebar widened on a large screen cannot crowd the page content once the window shrinks. The viewport clamp is applied over the stored preference rather than written back to it, so widening the window again restores the width the user chose. The bounds now live in sidebar/width.ts behind usePagesSidebarWidth, so the sidebar and the page header that aligns to its edge resolve the same width and the same live cap. The drag preview's own cap moves with them. See MM-70493. Context: /longshot https://mattermost.atlassian.net/browse/MM-70493
The row menu had no keyboard route on macOS. Shift+F10 and the Menu key were the only openers, and Apple keyboards have neither, so a page's actions were unreachable without a pointer. The trigger is now tabbable on whichever row holds the tree's roving tab stop, so the tree still reads as a single stop from the outside: Tab in, Tab again for that row's menu, Tab again out. Arrow keys already cover the chevron, so the menu is the only row control that needs its own stop. The screen-reader instructions name the new key. Collapsing the trigger to zero width when hidden is folded in here rather than split out: it reclaims 28px of every row for the page name, but it also turns the hidden trigger into a zero-size target, so the focus ring and the focus-visible reveal are what keep the new tab stop usable. Re-running the extractor also drops docs.share.visibility.public and publicHint from en.json. Both are unreferenced in source and predate this branch; webapp strings aren't covered by `make i18n-check`, which is how they drifted. See MM-70493.

The tab stop follows the focused row, but aria-selected follows the routed page, so "the selected page" named the wrong row as soon as an arrow key moved focus off the open page. The Alt+arrow sentence had the same slip and is corrected with it: a reorder acts on the focused row too, never on aria-selected. See MM-70493. Context: CodeRabbit review on PR #41

Not captured. Worth an eye on the hover re-truncation, since a long page name re-ellipsises as the menu button expands.
