* Make the path mappings relative so TypeScript 7 accepts them

TypeScript 7 removed `baseUrl` (TS5102) and rejects a non-relative target in
`paths` (TS5090), so `npm run typecheck` fails on the compiler this commit's
parent installs.

`baseUrl: "."` resolved the targets against this file's directory, and a `./`
prefix resolves them the same way without the removed option, so the four
mappings still point where they did. Nothing else reads them: vitest resolves
`@podiumstack/*` through `resolve.alias` in its own configs, so this is
confined to `tsc`.

The rewritten form compiles under 5.x as well as 7.x, which is why it belongs
in this PR rather than ahead of it.
