fix(apollo-react): default add-node search placeholder to "Search nodes" [MST-11831]

[KodudulaAshishUiPath]

Summary

• The add-node panel's search input showed a generic "Search" placeholder. Per the Flow building experience content audit, search placeholders should describe what will be searched.
• AddNodePanel now defaults its search placeholder to "Search nodes" (new lingui message add-node-panel.search-nodes).
• Both AddNodePanel and Toolbox expose an optional searchPlaceholder prop so hosts can pass scoped copy ("Search agents", "Search data nodes") per menu context.

Changes

• Toolbox: new optional searchPlaceholder prop; default behavior unchanged (lingui toolbox.search = "Search"), so other Toolbox consumers (e.g. StageNode) are unaffected
• AddNodePanel + AddNodePanel.types: pass-through prop, defaulting to "Search nodes"
• src/canvas/locales/en.json: add-node-panel.search-nodes entry (English only; translated catalogs land via the usual translator flow), kebab-cased to match the catalog's key convention

Testing

• Toolbox + AddNodePanel test suites pass, including new coverage for the searchPlaceholder prop: Toolbox renders a custom placeholder, AddNodePanel defaults to "Search nodes" and forwards a host override
• turbo run typecheck --filter=@uipath/apollo-react green; biome lint shows only pre-existing warnings
• Note: pnpm run i18n:extract currently fails repo-wide on a pre-existing duplicate id in ap-chat (autopilot-chat.error.multiple-files has two different default texts) — the catalog entry was added by hand and verified with i18n:compile

Pull request overview

Updates the canvas add-node search UX copy in @uipath/apollo-react so the placeholder describes what the user is searching, aligning with the referenced content audit guidance.

Changes:

• Added a new Lingui message id for the add-node search placeholder and defaulted it to “Search nodes” in AddNodePanel.
• Extended Toolbox with an optional searchPlaceholder prop (default remains the existing generic “Search”).
• Plumbed the optional searchPlaceholder through AddNodePanel so hosts can override it with context-specific copy.

_{"Coverage" is each package's own coverage.include scope (e.g. apollo-core instruments only scripts/). "Packed"/"Unpacked" come from npm pack --dry-run and only cover built packages — "—" means not measured this run (package not affected / not built). "vs main" is the packed (gzipped) delta against the last successful main build (the package-sizes artifact from the Release workflow); "—" there means no main baseline was available this run. The baseline is main's latest build, not this PR's exact merge-base, so it includes any drift since the branch diverged. Packages with no vitest config are omitted.}
