Applies the byRegexp(\\.min$ | \\.max$) → custom.lineStyle dashed pattern to
all 4 timeseries panels in config/machine.json — pattern confirmed via S2
spike (#33). Forward-compatible: nodes that don't yet emit .min/.max fields
see no change in rendering (regex won't match).
- config/machine.json: 4 timeseries panels gain byRegexp overrides for both
.min$ and .max$, dashed [10,10], orange (min) / red (max).
- test/basic/slice38-dashed-bounds.basic.test.js: 2 cases (presence per ts
panel, anchor-to-end forward compatibility).
Companion-field emission helper (generalFunctions.outputUtils — produces
<field>, <field>.min, <field>.max from a bounds-aware source) is a
generalFunctions submodule change and lands in a follow-up PR — out of
scope for this dashboardAPI-only slice.
Closes#38
