Closes#45847.
## Summary
`ProjectNeedsSecuringView.tsx` built the `View policies` href on the
first-time security gate by interpolating `table.schema` and
`table.name` directly into the URL. A table or schema containing `&`,
`=`, `+`, or `#` corrupted the destination and routed the user to the
wrong policies filter on what is meant to be a guided onboarding flow.
Extracts the URL into `getTablePoliciesHref` in
`ProjectNeedsSecuring.utils.ts` with `encodeURIComponent` wraps, and
replaces the inline interpolation. Same pattern as #45385.
## Test plan
Added `ProjectNeedsSecuring.utils.test.ts` covering
`getTablePoliciesHref` (plain values, special chars in name, special
chars in schema, both, undefined inputs) and pulling in the
previously-untested `getTableKey`, `formatRlsDescription`, `sortTables`,
and `buildSecurityPromptMarkdown` utilities. Ten tests total.
