#### Brief overview of PR changes/additions
Convert raw millisecond integer literals at time-duration call sites to
`std::chrono` literals, and add `#include <chrono>` to each touched
translation unit. Examples:
- `QTimer::singleShot(0, ...)` → `QTimer::singleShot(0ms, ...)`
- `mpTimerReplay->setInterval(1000)` → `setInterval(1s)`
- `mPendingTimer.start(60000)` → `start(1min)`
- `QObject::startTimer(50)` → `startTimer(50ms)`
- `QTest::qWait(100)` → `QTest::qWait(100ms)`
- `QThread::msleep(10)` → `QThread::sleep(10ms)`
This is a semantics-preserving refactor - every duration is kept exactly
equal to before (e.g. `1000` ms becomes `1s`, `60000` ms becomes
`1min`). No behavioural change.
#### Motivation for adding to Mudlet
Chrono literals make time durations self-documenting and type-safe. `1s`
/ `100ms` read unambiguously where a bare `1000` / `100` forces the
reader to remember each API's unit, and the compiler now rejects unit
mismatches. Only genuine duration arguments were converted - loop
counts, scroll-line counts, sizes, ports and the like were deliberately
left as plain integers.
All targeted APIs provide `std::chrono` overloads in the minimum
supported Qt (6.8.2): `QTimer::singleShot`/`start`/`setInterval` (5.8),
`QObject::startTimer` (5.9), `QThread::sleep(std::chrono::nanoseconds)`
(6.6) and `QTest::qWait(std::chrono::milliseconds)` (6.7).
#### Other info (issues closed, discussion etc)
Test case: the full application builds cleanly and the entire functional
`ctest` suite passes. The only failing test is the known, pre-existing
`PasswordMigrationTest` LSan exit-leak (GTK3/fontconfig noise), which is
unrelated to this change.

#### Brief overview of PR changes/additions
- TelnetServerStub now binds an OS-assigned (ephemeral) port; its log
reports the actual bound port
- All 11 functional tests that hardcoded listen ports (three shared port
4000, two pairs shared 4003/4004) now read the real port back via
serverPort()
#### Motivation for adding to Mudlet
Concurrent test runs (parallel CI jobs, multiple checkouts on one
machine) collided on the fixed ports, causing flaky bind failures and
tests connecting to the wrong run's server.
#### Other info (issues closed, discussion etc)
Follows the pattern GMCPCharLoginTest already used. Verified by running
two copies of TelnetTextDisplayedTest simultaneously - both passed on
distinct ports (37503/42303), impossible before.
**Test case:** Run the functional suite twice in parallel (two build
dirs or ctest -j2 repeated); no "address already in use" failures.

#### Brief overview of PR changes/additions
The Qt documentation for `QtConcurrent` points out:
> If you include the `<QtConcurrent>` header, the entire Qt Concurrent
module with the entire Qt Core module will be included, which may
increase compilation times and binary sizes. To use individual functions
from the QtConcurrent namespace, you can include more specific headers.
>
> The table below lists the functions in the QtConcurrent namespace and
their corresponding headers:
|Function|Header|
|--------|------|
|`QtConcurrent::run()`|`<QtConcurrentRun>`|
|`QtConcurrent::task()`| `<QtConcurrentTask>`|
|`QtConcurrent::filter()`,<br>`QtConcurrent::filtered()`,<br>`QtConcurrent::filteredReduced()`|`<QtConcurrentFilter>`|
|`QtConcurrent::map()`,<br>`QtConcurrent::mapped()`,<br>`QtConcurrent::mappedReduced()`|`<QtConcurrentMap>`|
#### Motivation for adding to Mudlet
To speed up the build a little by removing stuff that isn't needed.

In doing this I happened to start cleaning up a couple of header files
`T2DMap.h` and then `mudlet.h`, I then got into converting some
`#include`s into forward declarations in a "include-what-you-use" move.
This then rippled through into a (more than 10!) number of files but
should "improve" things.
Note that the ordering of `#include` in many files seems to be rather
haphazard and is due for some serious overhaul - I suggest that we
should actually declare an "official" style for this project so that
everyone knows what it is.
**During the CI/CB process I discovered that Linux and then MacOS builds
were failing because the file referred to by the `#include
<QtConcurrentTask>` header file was missing, yet was present on my local
PC when I was using the Qt framework from the On-line installer.
Initially I suspected a Debian (and then Devuan - as the packaged
version on my own machine also had this defect AND Ubuntu) package
problem; however it now seems to be an upstream Qt issue as the various
Qt versions & OS combinations suggest that Qt themselves fixed it for Qt
6.10:**
| OS | QtVersion | Missing header |
|--------|-----------------------|----------------|
| Windows| 6.11.0 package | No |
| Devuan | 6.8.2 package | Yes |
| Devuan | 6.10.0 online install | No |
| Ubuntu | 6.9.0 package | Yes |
| Debian | 6.8.2 package | Yes |
| MacOS | 6.9.0 package | Yes |
**To fix this I reverted to an `#include <qtconcurrenttask.h>` for Linux
and MacOS builds - although it would probably have been better to make
it conditional on the Qt Version instead...**
*I have reported this upstream to Debian - see:
