feat(sat): the Satellites tab laid out again, and a visible ground track

Everything asked for and not delivered last time.

The sky plot moves to its own column on the LEFT of the map. It was
stacked in the readout column, where a plot that wants to be square
competed for width with the numbers and pushed the pass table off the
bottom of the screen — while the margin on the other side of the map sat
empty throughout. Its own width, dragged from its right edge, with
double-click to reset.

Every block of the readout column gets a heading and a chevron: the
pass, the position, what to tune, the pass list. Each remembers its own
state, because an operator working FM birds never looks at the linear
passband and one watching a schedule never looks at the range rate.
There were no headings at all before, which cost twice — nothing said
what a group of numbers was, and there was nowhere to put the control
that shuts it. A shut block keeps the one number it exists for in its
heading, and drops that badge again when open rather than repeating the
body a line below.

The tune panel now leads with the CENTRE of the passband. The
Doppler-corrected figure was the wrong number for a reference panel: it
moves every second, it is different for every operator, and it is not
what the frequency plan, the AMSAT tables or anybody on the air calls
the satellite's frequency. What the radio is actually on belongs beside
Tracking, where the radio is — it is already there — so this keeps the
correction only as the offset that explains the difference.

Badges rather than rows of grey words, in the app's own status tones, on
the things that decide something: the band of each frequency, the
Doppler offset, an inverting transponder, the passband width, and the
peak elevation of a pass.

And the ground track. It was `color: 'var(--info)'` on a map that
renders with preferCanvas, and a CSS variable is not a colour a canvas
strokeStyle can take — so the browser kept whatever was set last and the
track came out a pale near-white that vanished over the imagery and the
deserts alike. This is the same trap internal to GridSquareMap's own
comment: every other map in this app passes hex. Now a real colour over
a dark casing, the way a road is drawn, because one line cannot hold up
over both a pale sea and a dark continent but a line with an outline
can.

+      "L’onglet Satellites est réagencé. Le tracé du ciel passe dans sa propre colonne à GAUCHE de la carte, où un graphique qui veut être carré ne dispute plus la largeur aux chiffres — il occupait la colonne de droite et repoussait le tableau des passes hors de l’écran, alors que la marge de l’autre côté de la carte restait vide. Sa largeur se règle à la souris, et un double-clic sur la poignée la réinitialise.",
+      "Chaque bloc de la colonne de droite a désormais un titre et se replie indépendamment : la passe, la position, ce qu’il faut accorder, la liste des passes. Chacun retient s’il est ouvert, car qui travaille les satellites FM ne regarde jamais la bande passante linéaire, et qui surveille un calendrier ne regarde jamais la vitesse radiale. Un bloc replié conserve dans son titre la seule chose utile : le décompte, l’élévation, le mode.",
+      "La fréquence à accorder est le CENTRE de la bande passante, pas la valeur corrigée du Doppler. Celle-ci bouge chaque seconde, diffère pour chaque opérateur, et n’est pas ce que le plan de fréquences ou n’importe qui sur l’air appelle la fréquence du satellite ; elle a sa place à côté de Tracking, là où se trouve la radio, et c’est là qu’elle est désormais. La correction reste ici, comme l’écart qui explique la différence entre les deux.",
+      "Plus de couleur là où elle décide de quelque chose : la bande de chaque fréquence, l’écart Doppler, un transpondeur inverseur, la largeur de bande passante et le pic d’élévation d’une passe sont des pastilles aux couleurs d’état de l’application, plutôt que des rangées de mots gris.",

Il était dessiné avec une variable CSS, qui n’est pas une couleur exploitable par un canvas : le navigateur conservait ce qu’il avait et le tracé sortait dans un blanc pâle qui disparaissait aussi bien sur l’imagerie que sur les déserts. C’est maintenant une vraie couleur, tracée sur un liseré sombre comme on dessine une route sur une carte — une seule ligne ne peut pas tenir à la fois sur une mer claire et un continent sombre, une ligne avec un contour si."
