Aleksei SviridkinandMatthieu ROBIN cca54d876a docs(operations): resource presets reference

Document the five instance-type series (t1/c1/s1/u1/m1) introduced
alongside the legacy preset deprecation, the per-size CPU and memory
matrix, and the 1:1 legacy-to-instance-type mapping table that powers
cozy-lib aliases, migration 39, and the operator-side deprecation
warning.

Single source of truth referenced from:
  - packages/library/cozy-lib/templates/_resourcepresets.tpl
  - packages/core/platform/images/migrations/migrations/39
  - pkg/apis/apps/presets/legacy.go

Includes an explicit callout that legacy `medium` (1 CPU / 1Gi) and
instance-type `*.medium` (2 CPU) are not the same — same word,
different resources.

Replace inline preset tables in packages/apps/postgres/README.md and
packages/apps/kafka/README.md with a short paragraph that names the
five series and points at the canonical doc, since the per-app
inline tables listed only the legacy seven and would drift further
as the canonical matrix evolves.

Parameter examples and reference

resources and resourcesPreset

resources sets explicit CPU and memory configurations for each replica. When left empty, the preset defined in resourcesPreset is applied.

resources:
  cpu: 4000m
  memory: 4Gi

resourcesPreset sets named CPU and memory configurations for each replica. This setting is ignored if the corresponding resources value is set.

Presets follow a cloud-style <series>.<size> naming convention. Five series cover the full CPU-to-memory ratio range (t1 1:0.5, c1 1:1, s1 1:2, u1 1:4, m1 1:8) and each series ships eight sizes (nano through 4xlarge). The legacy flat names (nano, micro, small, medium, large, xlarge, 2xlarge) remain accepted as deprecated aliases of their 1:1 instance-type equivalents.

See docs/operations/resource-presets.md for the full size matrix and the legacy-to-instance-type mapping.
