Fix external-link warning on tab navigation

Tab links use relative query-string hrefs (?tab=scheduler), which fail
every check in Unraid's global external-link click-guard (BodyInlineJS.php):
not a valid absolute URL, doesn't start with "/", doesn't match a
registered plugin page basename. Confirmed live — the guard's dom.hostname
ends up undefined for these, matching the reported "Always Allow undefined"
dialog text exactly.

Fix: add class="localURL", the same escape hatch dynamix's own pages
(ManagementAccess.page) use for this exact situation. Applied to the main
tab bar and the setup wizard's checklist action links (?tab=partnership).
