Fix console refresh focus and block-list feedback for v1.0.2

[drudge]

Live console refreshes can interrupt keyboard navigation, close controls, and overwrite unsaved edits. Adding a large block list also needs immediate feedback without moving the dialog. This prepares those fixes for v1.0.2.

Changes

• Keep routine dashboard polling visually quiet and update stat cards in place so focus and hover highlights do not pulse; loading feedback appears only for manual chart-range and overview-scope changes.
• Preserve stat-card and scope-control focus during live updates, protect open controls and backup drafts, and discard stale query-log responses after pausing or changing filters.
• Show a compact loader-circle while adding catalog or custom block lists, prevent duplicate submissions, and retain visible mobile Add icons. Manual add/update failures show error toasts, including connection interruptions and unrendered HTTP errors inside the open dialog.
• Show a seven-character commit SHA on mobile About pages while retaining the full value on larger screens and in the tooltip.
• Add focused browser regression checks for these behaviors, run them in CI, and include the matching v1.0.2 changelog section.

The behavior changes live in the existing internal/web/assets/app.js and page templates. Generated templ output accounts for most of the diff.

Validation

• go tool mage verify
• go tool mage race
• SABLE_TEST_BROWSER='/Applications/Google Chrome.app/Contents/MacOS/Google Chrome' go test -count=1 -tags=browser -run TestBrowser -v ./internal/web
• go mod verify
• Go formatting and git diff --check
• go tool govulncheck ./... — no reachable vulnerabilities

Release

Target version: v1.0.2. CHANGELOG.md contains the curated release notes. After merge and required CI, publish through the existing Release workflow with version 1.0.2; the workflow creates the annotated tag and injects the published version.
