Improve Admin Management UX: permissions, search, table, tooltips, and mobile fixes

[maxijabase]

Summary

This PR is a focused pass over Admin Management. It fixes the broken Edit Admins permission path, brings the admins list and search up to the current panel chrome, improves the edit-admin permissions editor, and closes a few mobile layout bugs along the way.

Permission fix

• Admins who hold Edit Admins (and are not Owners) can edit other admins again (fix Edit Admins not working as expected #1527).
• Details / password editing and the related UI gates follow that same rule.

Admins list and table

• Refreshed the admins list row actions and desktop table styling so it matches the rest of the panel.
• Kept permission tables usable on mobile by opting them out of the global hide-.table-under-768px rule (those forms need the table layout).

Advanced search

• Dropped Exact / Partial toggles. Name, Steam ID, and email always substring-match.
• Web and server permission filters use a themed multi-select over a real <select multiple>, so GET submit and no-JS still work.
• Fixed server-permission filtering: use aid (not authid), keep SM flags as characters, and allow SM_CUSTOM1 through SM_CUSTOM6 in the allowlist.

Edit admin (Details / Group / Servers / Permissions)

• Shared tab strip across all four edit-admin pages, including Permissions.
• Removed the empty AdminTabs Back strip that left dead space under the topbar.
• Put Back on the right of the in-page tab row (links to the admins list).
• Permissions editor: Select all per card, clearer category grouping (parent vs child rows), and section labels on the server flags table.
• Side-by-side Web / Server permission cards on wide screens, stacked on smaller ones.

Tooltips

• Restored the tooltip UI helper in sb.js / theme CSS so hover help works again where templates expect it.

Overrides mobile

• Add an override Type / Name / Flags stack on narrow viewports instead of overflowing the card (fix Group Override Text Wrapping #1380).

Test plan

• Log in as an admin with Edit Admins but not Owner. Open another admin and confirm Details / password save works.
• Admins list: row actions, desktop table, and mobile cards look correct.
• Advanced search: name / Steam / email substring search works without Exact/Partial.
• Advanced search: multi-select web + server permissions filter correctly, including custom SM flags.
• Edit admin tabs: Details / Group / Servers / Permissions share the same strip; Back returns to the admins list with no blank gap under the topbar.
• Permissions: Select all / category parent toggles / individual children behave as expected; save still works.
• Permissions on a phone-width viewport: tables stay visible.
• Overrides on mobile: Add an override fields stack and stay inside the card.
• Hover tooltips where the panel still uses them.
