fix(client): cold-start black screen — self-healing tile repaint, legend re-entry root cause, pending-tile wash

Jeroen hit a black mosaic zooming into a body from a fresh make-atlas
spawn. Live diagnosis showed all six tiles held with colored textures
and no repaint; the original line-specific diagnosis (unpaired
queue_redraw in _on_tile_ready) turned out WRONG — the pairing already
existed (lead's truncated grep misread the function; Stig verified via
git log -p before acting). Rather than chase the exact dropped signal
edge, _process() now self-heals: both viewer and overlay redraw every
frame while the tile set has pending tiles (has_pending_tiles(), new) —
a strict superset that closes the black regardless of which edge drops,
pinned by a _draw()-counting real-subclass spy test.

Legend stacking root cause found by trace, not guess: ImplantApp.
_on_screen_changed() re-runs enter() unconditionally on repeat
same-screen pushes — each re-entry tore down and rebuilt all six tile
requests (the round-6 orphaning fingerprint via a new trigger) and
stacked another legend (~10 deep, full-height dark panel). Fixed both
ends: ImplantPanel.clear() frees immediately (same-frame re-entrant
refresh can never observe stale children — protects every implant app),
and RegionalScreen.enter() no-ops for the same body (different body
still re-enters fresh). The load-bearing regression asserts an ARRIVED
TILE'S DATA survives a repeat push — node identity would not catch the
teardown (the tile-set Node is a fixed field; only its internals reset).

Cold-start UX: pending tiles now draw the single-window path's
COLOR_BORDER_FADE wash instead of raw background — a deriving mosaic
reads as loading, not broken.

Suites green (zoom_ladder 48, viewer 74, tile_set 20, overlay 30,
overlays 46 + 2 new files), gdlint clean, revert-verified throughout.

# BUG 1 — tile-mosaic paint self-heal.
# =============================================================================
## Counts real _draw() invocations — CanvasItem exposes no public
## "is a redraw pending" query in this Godot version, so the only reliable
## signal that queue_redraw() actually had an effect is the engine calling
## _draw() again on a subsequent frame. Subclasses the REAL AtlasWindowOverlay
## (not a duck-typed stub) so drawing still runs through the genuine
## production code path — this spy only adds counting, nothing else.

## On a cold server, a tile's window_ready can land well after entry's own
## paint window, and a live repro showed the mosaic staying black even with
## every tile held/textured — only resolving on an unrelated gesture.
## _process() must therefore queue a redraw on BOTH the viewer and the
## overlay every frame while any tile is still pending, regardless of
## whether the tile-arrival signal path painted correctly on its own. Proven
## here by swapping the REAL overlay for a _draw()-counting subclass right
## after entry (once the entry-time redraw has already resolved via a real
## frame), then calling _process() directly with NO input/gesture and
## confirming a further frame actually invokes _draw() again — revert-
## verified against a version of _process() with the self-heal removed
## (fails without it, since nothing else re-queues while idle).
