Release v1.1.0rc3

[iabaako]

Pull Request Summary 🚀

What does this PR do? 📝

Bumps the version from 1.1.0rc2 to 1.1.0rc3, now that both #288
(rc2 changelog/version bump) and #289 (project configuration
export/import + redesigned project picker) are merged to main.

Why is this change needed? 🤔

1.1.0rc2 was tagged before #289 merged, so the new project
configuration export/import feature and the redesigned project picker
weren't part of any published pre-release yet. This rc build makes them
available on Test PyPI for the team to try out.

How was this implemented? 🛠️

• Branched off origin/main directly (after confirming both Release v1.1.0rc2 #288 and
  feat: export/import project configuration + redesigned project picker #289 were merged, and that the changelog merge conflict between them
  had already been resolved on main)
• Ran just bump-and-tag rc (uv version --bump rc under the hood) to
  bump pyproject.toml from 1.1.0rc2 to 1.1.0rc3, re-synced
  uv.lock, and created the v1.1.0rc3 tag (already pushed, triggering
  the Release workflow / Test PyPI publish)

How to test or reproduce ? 🧪

This PR (version bump only, no source changes):

1. just lint-py — passes
2. just test — full suite green
3. just check-changelog rc — [Unreleased] gate passes
4. just version — confirms 1.1.0rc3

The published 1.1.0rc3 pre-release itself — once the Release
workflow finishes (check Test PyPI: DataSure history):

uv tool install "datasure==1.1.0rc3" --index-strategy unsafe-best-match \
    --index https://test.pypi.org/simple/ \
    --index https://pypi.org/simple/
datasure --version
datasure

Particularly worth checking against #289: the redesigned Start page
project picker (search/sort, per-project rows, "More" menu) and the
"New Project" → "From a configuration file" flow end-to-end.
