SoftFever feeea3e651 fix: treat renamed printer presets as compatible aliases (#14504)
# Description

Fixes user filament presets that reference an old printer preset name in
`compatible_printers`, even when the current system printer preset
correctly declares that old name in `renamed_from`.

## Core Issue

`PresetCollection::find_preset()` was updated to resolve `renamed_from`,
but this specific failure does not go through `find_preset()`.

For root user filament presets with empty `inherits`, Orca infers
`compatible_printers` from the filament name suffix after `@`. For
example:

```json
"ELEGOO PLA Base @Elegoo Neptune 4 Pro (0.4 nozzle)"
```

loads with:

```json
"compatible_printers": ["Elegoo Neptune 4 Pro (0.4 nozzle)"]
```

The current system printer preset is named:

```text
Elegoo Neptune 4 Pro 0.4 nozzle
```

and has:

```json
"renamed_from": "Elegoo Neptune 4 Pro (0.4 nozzle)"
```

However, filament compatibility was doing a direct string comparison
against the active printer name. Since that compatibility path does not
call `find_preset()`, the `renamed_from` mapping was never considered.

## Fix

Teach printer compatibility checks to treat
`active_printer.preset.renamed_from` entries as aliases of the active
printer name.

This preserves existing user preset JSON and avoids rewriting
`compatible_printers`, while allowing old printer suffixes to remain
compatible with renamed system printer presets.
