Adding version 2 filters

[sandboxcoder]

• Add missing filters (Luma Key, 3-Band Eq, and Upward Compressor)
• Add version 2 of all known filters that were updated
• Existing scenes will continue to work using any declared version 1 filter. But when user creates a new scene filter, they will receive the appropriate version 2 filter.

Regression test cases for QA

This PR updates the following filters: Image Mask/Blend, Color Correction, Color Key, Sharpen, Chroma Key, and Noise Suppression

This PR adds Upward Compressor (Audio filter), Luma Key Filter (Video), and 3-Band Equalizer (Audio filter)

Test cases (I tried):

• Existing scenes can keep using version 1 filter. User should not notice any change.
• If user adds a filter that has been updated such as "Color Correction" filter, then they will get the Version 2 filter.

What changed from version 1 to version 2?

Color Correction - v2 adds proper color space negotiation so the filter works correctly in SDR/WCG pipelines without mangling HDR content, whereas v1 blindly assumed GS_RGBA for everything.

Image Mask/Blend- v2 is a precision and color-pipeline upgrade — higher-resolution opacity and proper sRGB/color space awareness

Color Key Filter- v2 is a substantial rework: opacity is redesigned from an alpha-packed color hack into a proper float parameter, brightness scaling is removed, the contrast/brightness ranges are expanded, and the whole render path gains proper color space awareness.

Sharpness - only adds SRGB capability flag
Chroma Key - the chroma key v2 changes are a mirror of the color key v2 changes — opacity redesigned from an alpha-packed color hack to a proper float, brightness scaling removed, expanded ranges, and full color space pipeline awareness added.

Noise Suppression (Audio) - v2 promotes RNN (Recurrent Neural Network) noise suppression as the preferred default when available, rather than only falling back to it when Speex isn't present.

New filters that this PR exposes

Luma Key Filter:
The luma key filter makes pixels transparent based on their brightness (luminance) rather than a specific color. It exposes four parameters:

• Luma Min / Luma Max (0.0–1.0): defines the brightness range to key out. Pixels whose luminance falls within this range become transparent.
• Luma Min Smooth / Luma Max Smooth: softens the edges of the key at the min/max thresholds, so the transparency transition isn't a hard cut.

For example, with default settings (luma_min=0.0, luma_max=1.0, no smoothing), nothing is keyed. If you set luma_min=0.5, pixels darker than 50% brightness become transparent — useful for removing black backgrounds or applying overlays that blend based on brightness
rather than color.

It's commonly used with white/black backgrounds or as a way to composite elements where a color-based chroma key wouldn't work.

Upwards Compressor: The upward compressor is an audio dynamics filter that boosts quiet sounds up toward a threshold, as opposed to a traditional (downward) compressor which turns loud sounds down.

How it works:

1. Detection — measures the signal level using an RMS envelope follower (10ms window)
2. Gain stage — for signals below the threshold, applies positive gain proportional to slope * (threshold - signal_level). Signals above the threshold get 0 gain (left untouched). The slope is 1.0 - ratio, where ratio is 0.0–1.0
3. Knee — a soft knee (0–20 dB wide) smooths the transition around the threshold so the boost doesn't kick in abruptly
4. Ballistics — attack and release times control how fast the gain responds
5. Output gain — a final makeup gain stage

Parameters:

• Ratio (0.0–1.0): how aggressively to boost quiet sounds — higher ratio = more boost
• Threshold (-60–0 dB): the level below which boosting begins
• Attack / Release (1–100ms / 1–1000ms): how fast the gain reacts
• Knee width (0–20 dB): softness of the threshold transition
• Output gain (-32–+32 dB): makeup gain applied after compression

Practical use: leveling out a quiet speaker or microphone so soft parts of speech become more audible without turning up the overall volume

3 Band Equalizer: It's a simple 3-band equalizer audio filter. It splits the audio signal into three frequency bands and lets you boost or cut each by ±20 dB:

• Low — below 800 Hz (bass)
• Mid — 800 Hz to 5000 Hz (vocals, presence)
• High — above 5000 Hz (air, sibilance)

Pull request overview

Updates the app’s filter allowlist to surface newly added OBS filters and switch several existing filters to their updated “v2” identifiers, while adding missing UI strings for the new filter names.

Changes:

• Switched multiple existing filter type IDs to their _v2 variants (e.g., mask/color/chroma key/noise suppression).
• Added allowlisted entries for newly supported filters: Luma Key (v2), Upward Compressor, and 3-Band Equalizer.
• Added English (en-US) i18n strings for the new filter names.
