Add WPWE0-7 summary test cases

[GitPaean]

Adds twelve self-contained decks under wpwe/ to exercise the WPWE0-7
support introduced by opm-common#5352
and opm-simulators#7395.
This is a cases-first review: the event semantics can be agreed before reference
output and regression-suite registration are added.

Test decks

• WPWE-ACTIONX-TYPE-CONVERSION.DATA — converts a producer to an injector and back through ACTIONX, exercising WPWE6 and WPWE5.
• WPWE-COMPLUMP-CONNECTION-COUNT.DATA — shows that WPWE2 counts connections while the WPWE3 closed-to-bottom test operates on completions.
• WPWE-CON-PLUSCON.DATA — compares independent CON and +CON closures on one well and shows that both offending connections count towards WPWE2.
• WPWE-DECK-CONNECTION-CHANGES.DATA — exercises deck-driven connection closure and reopening, including suppression of WPWE1 while a well is stopped.
• WPWE-DECK-STATUS-CONVERSION.DATA — contrasts silent deck-driven SHUT/STOP changes with producer/injector conversions reported by WPWE6/WPWE5.
• WPWE-DECK-WELL-ADDITION.DATA — adds wells through WELSPECS during the run and verifies that schedule insertion is not a WPWE0 drilling event.
• WPWE-MIXED-CLOSURE-CAUSES.DATA — shows that WPWE3 depends on the remaining completion geometry rather than on what closed the other connections.
• WPWE-PLUSCON-CLOSURE-COUNT.DATA — verifies that the connection violating a +CON limit counts towards WPWE2.
• WPWE-TIMESTEP-PLACEMENT.DATA — distinguishes per-accepted-timestep event reporting from accumulation over a report interval.
• WPWE-UDQ-ACTIONX-NO-SUMMARY.DATA — uses WPWE2 from UDQ and ACTIONX without requesting a WPWE vector in SUMMARY.
• WPWE-WORKOVER-SHUT-STOP.DATA — distinguishes WPWE4 for a workover-stopped well from WPWE7 when no connection remains able to flow.
• WPWE-WTEST-REOPEN.DATA — verifies that an automatic WTEST reopen reports the number of reopened connections through WPWE1.

The economic-limit cases cross water-cut limits as the wells water out, which
spreads the events across each run. Exact event times can move with the timestep
sequence. Each deck's header states the question it asks, the wells and vectors
that answer it, and the measured behaviour.

The cases reuse the CECON-02 reservoir and initial wells. The grid and property
includes are copied into wpwe/include/ rather than referenced across
directories, so the cases can be handed over and run on their own.

Validation

The documented values were measured with flow_blackoil builds containing the
linked source changes. Serial and two-rank MPI runs produced the same sequence
of nonzero WPWE rows for every case.

Not included yet

• reference output
• registration in regressionTests.cmake

Those will follow after the cases and event semantics have been reviewed.

🟡 Changes recommended

The maintenance reference contains inaccurate timing and run-margin statements and overstates coverage of unrequested UDQ registration.

Pull request overview

Adds twelve self-contained WPWE0-7 simulation decks for reviewing event semantics before regression registration.

Changes:

• Covers connection, workover, conversion, ACTIONX, UDQ, and WTEST scenarios.
• Adds shared CECON-02-derived model data and summary configuration.
• Documents expected event sequences and maintenance guidance.

🔵 Needs a closer look

The numerical event sequences depend on specialized companion builds that cannot be independently validated in this review environment.

jenkins build this please

[GitPaean]

These are testing cases used to develop WPWE[0-7] event summary. Will pick some of them for regression tests. I am marking them as ready for review now.

[GitPaean]

The WPWE.md was generated during the case testing, adapted to the designed behavoir. At the same time, it might also increase the future maintenance purpose. Feel free to suggest to remove it.

[GitPaean]

After some thinking, I removed the WPWE.md file. It might not be used and it might be difficult to keep consistent.

Thank you so much for the effort in covering a multitude of cases. This looks good to me and I'll merge into master.
