fix(client): make the Rules dashboard table fill the available width

[serendipty01]

Context & Requests for Reviewers

fixes #1228
Table.tsx defaults its container to w-fit when containerClassName isn't set, so several dashboard tables only ever took their columns' intrinsic width, leaving a growing gutter on wide screens. Opts the Rules dashboard, and (second commit) Item Types, Actions, Reporting Rules, Text/Location/Hash Banks, and Manage Users into w-full, matching the dashboards that already had it (MRT queues, recent decisions, NCMEC reports, ...).

Added a second commit: containerClassName="w-full" for the same bug on the remaining dashboard-list tables (Item Types, Actions, Reporting Rules, Text/Location/Hash Banks, Manage Users). Same root cause — Table.tsx defaults to w-fit.
