Ruben Fiszel f0301b1605 feat(flows): preserve step/subflow worker tags under a custom-tagged flow (#9375)
* feat(flows): preserve step/subflow worker tags under a custom-tagged flow

A flow running on a custom worker tag force-propagates that tag to every
descendant step, script and nested sub-flow, overriding their own declared
tags. This made it impossible to route a specific step or sub-flow to a
different worker group. The new opt-in FlowValue.preserve_step_tags lets a
step that declares its own non-empty tag run on it; untagged steps still
inherit the flow tag. Defaults off to preserve existing behavior.

* chore: regenerate system prompts for preserve_step_tags

* feat(flows): nest preserve_step_tags toggle under flow worker tag setting

The toggle only affects routing when the flow has a custom worker tag, so
show it as a sub-setting of the Worker Group tag picker, visible only once a
tag is set, instead of as a standalone option.

* fix(flows): allow step worker tag picker when preserve_step_tags is enabled

When a flow defines a worker tag, the per-step tag picker was replaced by a
read-only "Flow's WG" label. With preserve_step_tags enabled the step's own
tag is honored, so the picker must remain editable in that case.

* fix(flows): propagate preserve_step_tags to branch and loop bodies

payload_from_modules built the synthetic RawFlow for branch/loop bodies with
a default FlowValue, dropping preserve_step_tags. Tagged steps inside a
branch or loop therefore still inherited the parent flow tag even with the
flag enabled. Thread the flag through to the synthetic FlowValue so the
behavior is consistent for nested containers.

* fix(flows): clear preserve_step_tags when flow worker tag is removed

Avoids the flag lingering as invisible state after the flow tag (and its
toggle) are removed.

* fix(flows): repair preserve_step_tags propagation to branch/loop bodies

The previous commit added flow.preserve_step_tags at the payload_from_modules
call sites but the parameter and FlowValue field were not actually threaded
through (a failed edit left the function unchanged), so the crate did not
compile. This completes the change: payload_from_modules takes preserve_step_tags
and sets it on the synthetic FlowValue for branch/loop bodies.

* fix(flows): complete preserve_step_tags propagation to branch/loop bodies

Previous two commits left windmill-worker uncompilable: payload_from_modules
received flow.preserve_step_tags at its call sites but the parameter and the
synthetic FlowValue field were not actually added. This adds the parameter,
sets preserve_step_tags on the synthetic FlowValue, and threads
flow.preserve_step_tags through all five call sites.

* fix(flows): clear preserve_step_tags whenever the flow worker tag is removed

The flag was only reset when the Worker Group toggle was switched off, not
when the tag was cleared directly in the picker (or via the YAML editor),
leaving preserve_step_tags=true as invisible state with the advanced badge
still reporting it active. Move the cleanup into the reactive block that
already tracks the flow tag so every clear path is covered.
