Fix all Checkstyle violations (#16)

* docs: fix all Javadoc warnings from Checkstyle

* fix: add braces to single-statement if blocks

* fix: AvoidEscapedUnicodeCharacters Checkstyle

* fix: wrap long lines in license headers

Checkstyle ignores URLs when enforcing line length, so this previously passed.
A prior commit reformatted the headers but missed the GPL notice block, which
is now wrapped correctly.

* fix: wrap long string literals to comply with line length limit

* refactor: replace wildcard imports with explicit imports

* refactor: move variable declarations closer to their first usage

* refactor: rename parameter from bEditable to editable in setEditable methods

* refactor: rename invalidIpAddressException to InvalidIpAddressException

* refactor: rename ipAddressValidator to IpAddressValidator

* style: standardize TODO comment format with colon separator

* refactor: rename EPPuplink to EppUplink

* refactor: rename EPPthread to EppThread and remove unused imports

* refactor: rename EPPthread field to eppThread for consistent naming

* refactor: rename EPPuplink field to eppUplink for consistent naming

* feat: add logging for exception handling in DbExporter

* refactor: rename GUI components and improve code style in MessageManagement and MessageDetail

* refactor: rename EPPparams to EppParams for consistent Java naming conventions

* refactor: improve variable naming and code style in ContactSelection and AddressPanel2

* refactor: rename GUI components in TxtImport and improve code style

* refactor: standardize variable naming and rename generic GUI components

* refactor: rename ManageParameters form file and standardize component names

* Add detailed logging for exception handling across application

* fix: add missing break statements and default cases in switch blocks

* refactor: resolving all the remaining Checkstyle violations

* refactor: fix comment punctuation in ContactsManagement

* refactor: remove unused panel and rename chkDnssec to chkDnsSec for consistent naming
