fix(api): flatten apps/api dist build output

[siddhanttiwari19]

Remove the paths override for @meridian/shared and @meridian/stellar-sdk-helpers in apps/api/tsconfig.json — workspace symlink resolution already reaches both packages' own dist without it. Add an explicit rootDir: src, matching the #349 fix for stellar-sdk-helpers, so a stray inclusion can't silently change the output layout again.

Also adds a CI check verifying apps/api/dist/index.js lands flat, per collinsezedike's suggestion on the issue.

Fixes #350

Summary

• apps/api/tsconfig.json had a paths override pointing @meridian/shared
  and @meridian/stellar-sdk-helpers at their raw src directories, the
  same misconfiguration fixed in fix(web): validate faucet XDR and env-configure the faucet URL #349 for stellar-sdk-helpers. Without an
  explicit rootDir, TypeScript inferred the common ancestor across all
  three src trees as the build root, so pnpm --filter @meridian/api build
  produced dist/apps/api/src/index.js instead of a flat dist/index.js —
  confirmed by reproducing the bug before applying this fix.
• Removed the paths override and baseUrl, and set an explicit
  "rootDir": "src", mirroring the exact fix applied in fix(web): validate faucet XDR and env-configure the faucet URL #349. Workspace
  symlink resolution already reaches both packages' own dist output via
  their package.json main field, so no override is needed.
• Added a CI step to lint-typecheck that builds @meridian/api and
  asserts apps/api/dist/index.js exists, so this can't silently regress a
  third time (per collinsezedike's suggestion on the issue).

Test plan

• pnpm lint && pnpm typecheck && pnpm test pass locally
• Reproduced the bug on main first (rm -rf apps/api/dist && pnpm --filter @meridian/api build → nested dist/apps/api/src/index.js), then confirmed this branch produces a flat dist/index.js
• Full workspace pnpm typecheck — 6/6 tasks pass
• Full workspace pnpm test — 7/7 packages, 163 tests pass
• pnpm format:check — clean

Closes #350

Nice work on this one. Root cause correctly identified, and the fix mirrors #349 exactly.

Good to merge!
