Delta for multi-device-eq

Existing spec: openspec/specs/multi-device-eq/spec.md (device-event resolve-and-apply, first-seen bootstrap, cold start, connect-disconnect- reconnect cycle, toggle-off behavior). None of that resolution logic changes. This delta only ADDS a requirement about where the per-station editing surface is reached from, and pins that the relocation has zero effect on resolution. Traceable to WU14 (shares WU13's editor component).

ADDED Requirements

Requirement: Per-Station EQ Entry Relocates, Resolution Logic Does Not

The per-station EQ editing surface MUST be reachable from the player's tool tray (see eq-custom-presets). This relocation MUST NOT alter the existing 4-level resolution hierarchy (matrix -> station -> device -> global) or any of its resolve-and-apply, first-seen-bootstrap, cold-start, or connect/disconnect/reconnect behavior.

Scenario: Editing per-station EQ from the player uses the existing hierarchy

• GIVEN a station has an existing entry in presetsMatriz or presetsPorEmisora
• WHEN the user edits it via the player's per-station EQ sheet
• THEN the change persists through the same resolution path already covered by multi-device-eq's existing tests
• AND device-change resolve-and-apply behavior for that station is unaffected

Scenario: Existing multi-device-eq test suite is unaffected (regression guard)

• GIVEN the existing multi-device-eq scenarios (device-event resolve-and-apply, first-seen bootstrap, cold start, connect-disconnect-reconnect, toggle-off)
• WHEN the per-station entry point relocates to the player
• THEN every one of those scenarios continues to pass unmodified
