* fix(flutter): shrink the unzoomed remote cursor by DPR on macOS and Linux
With "Zoom cursor" off in Adaptive or Custom view, the remote cursor
bitmap was registered at scale 1.0. NSCursor and GdkCursor treat the
bitmap size as logical pixels, so on a HiDPI controller the cursor was
drawn DPR times larger than in Original view (which already passes
1/DPR) and than on Windows (whose cursor path is in physical pixels).
A HiDPI remote such as KDE Wayland sends a 48-64 px bitmap, which then
showed up 3-4x too big on a Retina Mac.
Scale the bitmap by 1/DPR in that case, and scale the Flutter-painted
cursor used while the peer moves the mouse the same way so its size
does not jump. The new branch is an identity at DPR 1 and the Windows
paths are untouched.

* fix(flutter): check the cursor height against the min cursor size
`_checkUpdateScale` computed the scaled height from `width`, so the
min-size clamp never looked at the height.

* fix(flutter): keep the painted cursor hotspot in place when zoom cursor is off
`CursorPaint` subtracted the hotspot in remote pixels and then scaled it
by the canvas scale, but drew the image at scale 1.0, so the hotspot
landed hotx * (1 - scale) logical pixels away from the remote cursor
position. Cursors with a centered hotspot (I-beam, crosshair) were off
by up to half their size in Adaptive view. Subtract the hotspot after
scaling the position instead.

* fix(flutter): read the live DPR and clamp the painted cursor like the native one
CanvasModel caches devicePixelRatio and only refreshes it when the view
style changes, so after the window moves to a monitor with a different
DPR the unzoomed cursor kept the previous monitor's scale. Read it from
MediaQuery instead, which also rebuilds the cursor when it changes.
The native path clamps the scaled bitmap to kMinCursorSize; apply the
same clamp to the painted cursor so a small cursor does not change size
when the peer moves the mouse.

* fix(cursor): use `1.0` instead of `1.0/dpr` on Linux -> macOS, Zoom off, Scale adaptive
The mouse cursor currently appears somewhat large.
However, this is difficult to adjust because the cursor size
is fixed while the window size varies; its relative size
depends on the specific desktop environment.
We can modify it if users actually provide feedback.
Ideally, we should check the "Zoom cursor" option.
Further adjustments may also be needed later based on cursor density.

The row was added for the web client, which has no session tab to name
the transport on, but nothing gated it: a desktop session over WebRTC
showed it too, duplicating the tab tooltip's "(WebRTC)". The getter now
answers only on the web, as its own comment intended.

* fix(terminal): send SGR mouse wheel reports with the button codes apps expect
xterm.dart 4.0.0 encodes the wheel buttons as 64+4..64+7 rather than
64+0..64+3, so the low bits land on the modifier field and every wheel
report the terminal emits reads as wheel-with-Shift. Strict full-screen
applications reject the modified event, which is why neither the mouse
wheel nor the trackpad scrolls anything once the peer application takes
over the alternate screen.
Install a mouse handler that keeps every upstream reporting decision and
only re-encodes the wheel buttons as 64..67. Non-wheel reports pass
through untouched, and the emitted bytes stay identical once upstream
ships the same fix, so this can be dropped without a behavior change.
Upstream: TerminalStudio/xterm.dart#238

* fix(terminal): correct the wheel report row, drop the wasted report build
Address review feedback on the wheel button fix:
- The X10/utf row was encoded as `32 + y + 1` while y is already 1-based, so
every normal-mode report pointed one row too low and the `y > limit` guard
disagreed with what it emitted.
- Gate the wheel path on `mouseMode.reportScroll` and the button state instead
of building and discarding a full report string from `defaultMouseHandler`
on every scroll tick. This also makes the hardcoded SGR 'M' provably right,
since a wheel release now returns before the report is built.
- Derive the wire code as `id - 4` and drop `_wheelButtonId`, whose `default`
branch was unreachable and defeated enum exhaustiveness.
- Assign `mouseHandler` after construction so the `Terminal(...)` line stays
untouched.
Cover the utf, urxvt, null-byte overflow and click-only branches, and assert
that TerminalModel actually installs the handler.
