decodeHtmlEntities (duplicated in src/helpers.ts and
src/commands/detail.ts) only handled decimal numeric character
references (é); the equally valid hexadecimal form (é) fell
through undecoded and surfaced as raw text in titles, companies,
locations and descriptions. This bites Danish content especially
(ae/o/aa often arrive as entities). It also used String.fromCharCode,
which corrupts supplementary-plane code points (e.g. emoji, U+1F600).
Add a hexadecimal numeric-entity rule and route both decimal and hex
through a fromCodePoint-based helper with a valid-range guard, in both
copies. Add network-free unit tests via the exported parseJobCards.
