`PSPlaceOpenBrace` and `PSPlaceCloseBrace` leave trailing whitespace when expanding one-line blocks

[kjanat]

Steps to reproduce

Format a one-line block with IgnoreOneLineBlock = $false:

Invoke-Formatter -ScriptDefinition "if (`$x) { BREAK }" -Settings @{
    IncludeRules = @(
        'PSPlaceOpenBrace'
        'PSPlaceCloseBrace'
        'PSUseConsistentIndentation'
        'PSUseCorrectCasing'
    )
    Rules = @{
        PSPlaceOpenBrace = @{
            Enable = $true
            OnSameLine = $true
            NewLineAfter = $true
            IgnoreOneLineBlock = $false
        }
        PSPlaceCloseBrace = @{
            Enable = $true
            NewLineAfter = $true
            IgnoreOneLineBlock = $false
        }
        PSUseConsistentIndentation = @{ Enable = $true }
        PSUseCorrectCasing = @{ Enable = $true }
    }
}

Expected behavior

Expanding the block should not introduce trailing whitespace:

if ($x) {
    break
}

Actual behavior

The output contains a trailing space after break. The ␠ below marks that space:

if ($x) {
    break␠
}

The brace corrections replace only the brace tokens. The spaces that separated the one-line content from the braces survive as trailing whitespace after the block is expanded.

#1992 and merged #1993 are related, but not duplicates. They make PSAvoidTrailingWhitespace available to Invoke-Formatter when explicitly configured. They do not prevent PSPlaceOpenBrace and PSPlaceCloseBrace from introducing trailing whitespace. Callers should not need a separate cleanup rule to remove whitespace created by the formatter itself.
