web: a film sim is colour and tone only

The ten PHOTO STYLE sims now carry nothing but their stock's own grade, and
each is named for the stock it stands for: PROVIA, VELVIA, CLASSIC CHROME,
CLASSIC VIVID (Velvia spliced with Classic Chrome at the blue row), CLASSIC
NEGATIVE, ASTIA, ETERNA, ACROS, LC STREETLIFE CLASSIC, LC STREETLIFE VIVID.
Grain, clarity, saturation and light moves were dropped from their
`adjustments`, so a sim is a clean starting point and the general knobs read
their defaults while the look still lands on the pixels.

LC STREETLIFE VIVID keeps the one brightness step its stock needs, but as
SIM_EXPOSURE_BIAS in colorUtils rather than as an adjustment: it is folded in
where the Exposure slider applies, so the picture gets the lift and the
parameter stays at 0.

Also in this checkpoint: the watermark/GPS boxes and their colour pickers, the
WATERMARK chip column, the real admin stats, and the fix that stopped presets
from doubling and a frame from refusing to come off when a photo was reopened
(/file is the finished render, /base the editable pixels).

+// A sim carries exactly two things: its `baseFilter` colour matrix
+// (colorUtils.ts) and, where the stock needs to shape one end of the curve, its
+// FILM_TONE entry (toneShader.ts). Everything the sim does to the picture is in
+// those two places — including the brightness a stock owns: that is folded into
+// the matrix through SIM_EXPOSURE_BIAS (colorUtils.ts), never into
+// `adjustments`. `adjustments` is therefore the neutral default for every sim —
+// no grain, no clarity, no saturation push, no exposure/highlight/shadow move —
+// because those are the user's knobs, not the stock's. A sim is a clean starting
+// point, never a baked recipe; any further look is added afterwards.
