feat(salary): concept Löner landing + nav collapse animation (UI migration PR 9) (#1130)

* feat(salary): concept scene 22 landing + smoother nav collapse

Loner gets the concept header (quiet Anstallda link + Starta lonekorning
primary), the hero de-cards to a flat serif line + description + pill,
and the runs list becomes the scene 22 dry-table (Period, Status,
Anstallda, Bruttolon, Netto) where booked runs read as muted text and
in-flight runs carry a chip plus the payout date. Attention cards and the
hero state machine survive unchanged.

Nav polish: the collapse now animates as one movement (300ms decelerating
curve on both the aside width and the panel margin) and the rail/full
contents slide+fade in on swap; the Register/Bokslut folds match the
RowFoldout timing.

* refactor(salary): strip hero and attention cards from the landing

Founder direction: the Loner landing is header + lonekorningar only
(concept scene 22). The open run's table row is the entry point; AGI,
skatt, blockers and semester surfaces live on the run detail and the
employee register. Drops the hero state machine, the four cards, and all
their data plumbing (deadlines query, tax-payment chain, SKV status,
AGI submission hook).

* fix(salary): drop the Lonekorningar eyebrow

Founder feedback: the uppercase eyebrow read as a stray font above the
table, and with the landing reduced to the runs table alone the label is
redundant under the Loner page title.

* fix(salary): populate the Anstallda column via a count embed

The runs list selected bare salary_runs rows, so the landing's Anstallda
column was always empty (the employees array only ever existed on the
detail response). The list now embeds employee_count via
salary_run_employees(count) and the page reads the PostgREST count shape.

* fix(salary): quiet beige chip for in-flight run states

Founder feedback vs the concept: the Granskning chip rendered as the
bordered ochre warning badge and read noisy next to the concept's quiet
Utkast chip. Draft/review/approved now all wear the beige secondary chip;
the payout-date note carries the urgency.
