What this PR does and why

Deploy (modules/swiss and modules/inferences):

• A Preset select appears when the site profile lists presets, defaulting to none.
• Picking one shows its description and its values as YAML.
• The web merges the preset into the form layer it builds:
  • maps merge;
  • a list keeps the preset's items and adds the form's it lacks, ignoring key order;
  • a value the form sets wins.
• Compose and apply are unchanged.

Upgrade (both modules): there is no preset concept on upgrade.

• The web rebuilds the whole form layer, the release's own with the form's values over it, and sends it.
• Affinity: every rule in affinity and in each pd.<role>.affinityReplace shows as a YAML box you can edit, or remove and undo. That includes the GPU product term. Compose stays disabled while a box doesn't parse.
• Tolerations: they come back exactly as deployed.
  • Kept now: a toleration with no key (it tolerates every taint), tolerationSeconds, and a missing operator read as Equal.
  • Before, the first two were dropped and a missing operator was read as Exists.
  • Removing every row sends [].

Site profile pages (both):

• The page shows a Presets section.
• The edit form has a Presets section: each preset is listed with edit and remove.
• A dialog takes the name, description and values as YAML. It stores the preset only once the name is set and unique and the values parse to a map.

Shortcomings: swissd still merges an upgrade over the release's form layer, so a map key the web leaves out stays. That decides how the last item of a list is removed:

Removed	Sent
a role's last affinity rule	pd.<role>.affinityReplace: null, which the chart reads as inherit
the last required node term	the required block as null, since Kubernetes refuses an empty nodeSelectorTerms
the last item of any other list	[]

modelsphere/swiss#56 tracks storing the form layer exactly as sent. That issue also covers:

• switches the form always sends, so a preset can't set them;
• the GPU product term that swissd writes over the form's while products are picked.

Which issue(s) this PR fixes

Needs modelsphere/swiss#57 (swissd parses presets).
Refs modelsphere/modelsphere#57 (item 3), modelsphere/swiss#56.

How it was tested

• formLayer.test.ts:
  • preset merge and list de-duplication;
  • overlay onto the release's form layer;
  • listing affinity rules, editing them (strings stay strings) and invalid YAML;
  • writing the lists back, including the [] and null cases;
  • tolerations round-tripping exactly, an edited row keeping tolerationSeconds, and removing every row.
• profile.test.ts: a preset's row round-trip, its name and values errors, and renaming, adding and removing.
• Not tried in a browser or on a cluster.

Checks

• npm run typecheck && npm test && npm run build in web/ (613 tests)
• No internal hostnames, IPs, registries or credentials

Notes for reviewers

Start with web/src/modules/swiss/lib/formLayer.ts and affinity.ts, then planRequest in DeploySettings.tsx.

Release note

Deploy can pick a site profile preset. Upgrade shows the release's affinity and tolerations exactly, each one editable or removable. Needs a swissd that accepts the profile's presets.
