Bump python dependencies

[FlorentinD]

Consolidated update of python-wrapper dependencies via uv lock --upgrade,
plus bumps to exact-pinned dev tools: ruff 0.15.17->0.16.3, mypy 2.1.0->2.3.0,
pytest 9.0.3->9.1.1, selenium 4.44.0->4.47.0. streamlit (floor pin) and sphinx
(capped for py3.10/enum_tools compat) are intentionally left as-is.

Also switch the dependabot python-wrapper ecosystem from pip to uv so it
keeps uv.lock in sync going forward, and set open-pull-requests-limit to 10.

Supersedes dependabot PRs #421 #420 #415 #408 #405 #402 #401 #400 #390 #386
#385 #381 #380 #378 #377 #362 #356.

Semgrep identified an issue in your code:
This Dependabot configuration does not set a cooldown period. Newly published packages can be malicious or unstable. Add a cooldown block with default-days: 3 to each package-ecosystem entry under updates to wait 3 days before proposing updates to newly published package versions. Reference: https://docs.github.com/en/code-security/dependabot/dependabot-version-updates/configuration-options-for-the-dependabot.yml-file#cooldown

To resolve this comment:

✨ Commit fix suggestion

1. Add a cooldown block to this uv entry under package-ecosystem.
2. Set the cooldown to at least 3 days by adding default-days: 3.
3. Place it alongside the other top-level keys for that update entry, for example after package-ecosystem:
   cooldown:
default-days: 3
4. Keep the value numeric, not quoted, so Dependabot reads it correctly as 3.
