Textfield placeholders for edit mode only

[MBreathe]

This pull request makes placeholder values only visible when editing on multiple tabs across the Trainee Profile page. In addition, it fixes a styling bug for the Contact tab, where before the width was set to 90ch and now it is more flexible and set to 100%.

IN ADDITION
(this was achieved by running npm audit fix for client/ and server/)

This pull request updates several dependencies in the client/package-lock.json file, focusing mainly on upgrading the rollup platform-specific packages, minimatch, and ajv to their latest versions. These updates primarily address security, compatibility, and stability improvements.

Dependency upgrades:

• Rollup platform-specific packages: Upgraded all @rollup/rollup-* packages from version 4.57.1 to 4.59.0, covering various platforms and architectures (e.g., Android, Darwin, Linux, Windows, FreeBSD, OpenBSD, OpenHarmony). This includes the addition of explicit libc fields for Linux variants.

• Minimatch: Upgraded minimatch in several places:

  • From 3.1.2 to 3.1.5 for dependencies under @eslint/config-array, @eslint/eslintrc, and eslint.
  • From 9.0.5 to 9.0.9 for the main minimatch dependency, with a minor update to the brace-expansion dependency.

• Ajv: Upgraded the ajv JSON schema validator from 6.12.6 to 6.14.0.
