FEAT: Add a Message Manager for App

[dipinknair]

Fixes #440

from ansys.mechanical.core import App
app =App()

# Add a custom message
app.messages.add("info", "User clicked the start button.")

# check number of messages
len(app.messages)
... 1

# returns panda data frame representation
app.messages
... Severity             TimeStamp                   DisplayString Source StringID                                Location RelatedObjects
... 0     INFO  1/30/2025 1:46:14 PM  User clicked the start button.   None     None  Ansys.ACT.Core.Utilities.SelectionInfo             []
# print minimalistic view (severity and message)
app.messages.show()
... Severity: info
... DisplayString: User clicked the start button.

# prints all information including location, time, source etc of all message available
app.messages.show(filter='*")
... TimeStamp: 1/30/2025 1:42:01 PM
... Severity: info
... DisplayString: User clicked the start button.
... Source: None
... StringID: None
... Location: Ansys.ACT.Core.Utilities.SelectionInfo
... RelatedObjects: System.Collections.Generic.List`1[Ansys.Mechanical.DataModel.Interfaces.IDataModelObject]

# gets specific message in datafram row representation
print(app.messages[1].Severity)
... Info

# Remove specific message
app.messages.remove(1)

# Clear all messages
app.messages.clear()

An on/off for complete_info seems inflexible. How about this:

app.messages.show(filter="*") # filter defaults to "severity;message". Accepts a semicolon delimited list of columns or a wildcard.

@koubaa When app starts there is already a warning message saying license checkout is delayed. This was causing all the tests to fail because how test is written assuming zero message at the beginning.
