chore: bump Backstage to 1.55.1 and refresh vulnerable dependencies - #67

Conversation
Clears most audit findings (8 critical/85 high down to 0 critical/2 high), including runtime ones in fast-xml-parser, fast-uri, js-yaml, lodash and react-router. Adds @backstage/cli-defaults ahead of the CLI fallback removal.
The trailing semicolon in marginLeft made React drop the style, and the dev proxy still used v2-style onProxyRes/onError, which http-proxy-middleware v3 silently ignores.

The lockfile had drifted: yarn audit reported 8 critical and 85 high advisories, including runtime deps like fast-xml-parser, fast-uri, js-yaml, lodash and react-router. Bumping Backstage to 1.55.1 and refreshing transitives brings that to 0 critical / 2 high. The remaining two are adm-zip (dev-only, via module-federation in the Backstage CLI) and js-cookie via react-use (no fix in range).
http-proxy-middleware stays on 3.x (^3.0.7) since v4 is a major. @backstage/cli-defaults is added now because the CLI warns its built-in fallback is going away.
Also fixes two small bugs found while testing the dev app: a trailing semicolon in
marginLeftmade React drop the link icon margin, and the dev proxy used v2-styleonProxyRes/onErrorhooks that v3 ignores, so it never logged.Bumps version to 1.5.1, so merging triggers a release. Supersedes the open Dependabot PRs.
