## Add non-uniform border radius support to TableBorder
This PR extends TableBorder to support border radius even when the outer
border sides have different widths but the same color, similar to the
non-uniform border support added to Border in #121921.
### Changes
- Enhanced border rendering logic: TableBorder can now apply border
radius when outer border sides have uniform colors but non-uniform
widths/styles
- New helper methods: Added `outerBorderIsUniform` property and
`distinctVisibleOuterColors()` method to determine border uniformity
- Optimized paint method: Refactored the paint logic to handle three
scenarios:
1. Fully uniform borders (existing optimized path)
2. Outer borders with uniform colors but non-uniform widths (new
non-uniform border radius support)
3. Completely non-uniform borders (fallback to standard border painting)
### Before/After
- Before: TableBorder with border radius required all sides (including
inner borders) to be completely identical.
- After: TableBorder with border radius only requires outer border
colors to be the same, allowing different widths per side.
### Example Usage
```dart
TableBorder(
top: BorderSide(color: Colors.blue, width: 3.0),
right: BorderSide(color: Colors.blue, width: 1.0), // Different width
bottom: BorderSide(color: Colors.blue, width: 2.0), // Different width
left: BorderSide.none, // No border
horizontalInside: BorderSide(color: Colors.red, width: 1.0), // Different color OK
verticalInside: BorderSide(color: Colors.red, width: 1.0), // Different color OK
borderRadius: BorderRadius.circular(8), // ✅ Now works!
)
```
Fixes: #173193

This auto-formats all *.dart files in the repository outside of the
`engine` subdirectory and enforces that these files stay formatted with
a presubmit check.
**Reviewers:** Please carefully review all the commits except for the
one titled "formatted". The "formatted" commit was auto-generated by
running `dev/tools/format.sh -a -f`. The other commits were hand-crafted
to prepare the repo for the formatting change. I recommend reviewing the
commits one-by-one via the "Commits" tab and avoiding Github's "Files
changed" tab as it will likely slow down your browser because of the
size of this PR.

Originally, my aim was just to refactor (as per usual), but while messing around with the `TableBorder.symmetric` constructor, I realized that `borderRadius` was missing!
This pull request makes a few class constructors more efficient, and it fixes#144277 by adding the missing parameter.

* Update project.pbxproj files to say Flutter rather than Chromium
Also, the templates now have an empty organization so that we don't cause people to give their apps a Flutter copyright.
* Update the copyright notice checker to require a standard notice on all files
* Update copyrights on Dart files. (This was a mechanical commit.)
* Fix weird license headers on Dart files that deviate from our conventions; relicense Shrine.
Some were already marked "The Flutter Authors", not clear why. Their
dates have been normalized. Some were missing the blank line after the
license. Some were randomly different in trivial ways for no apparent
reason (e.g. missing the trailing period).
* Clean up the copyrights in non-Dart files. (Manual edits.)
Also, make sure templates don't have copyrights.
* Fix some more ORGANIZATIONNAMEs
