revert: tea 1.0 rewrite (#1122–#1126) (#1146)

Reverts #1126, #1125, #1124, #1123 and #1122. `go.mod` keeps the Go 1.26 line with toolchain `go1.26.9` (instead of the original `go1.26.6`) so the security fix from #1131 isn't lost. reopens #69 reopens #141 reopens #162 reopens #172 reopens #197 reopens #232 reopens #240 reopens #246 reopens #323 reopens #325 reopens #326 reopens #328 reopens #344 reopens #351 reopens #373 reopens #403 reopens #406 reopens #417 reopens #430 reopens #457 reopens #480 reopens #482 reopens #489 reopens #490 reopens #498 reopens #500 reopens #504 reopens #510 reopens #516 reopens #523 reopens #556 reopens #560 reopens #569 reopens #571 reopens #602 reopens #632 reopens #633 reopens #643 reopens #666 reopens #670 reopens #672 reopens #677 reopens #683 reopens #697 reopens #726 reopens #737 reopens #770 reopens #779 reopens #804 reopens #817 reopens #831 reopens #833 reopens #834 reopens #908 reopens #966 reopens #1023 reopens #1029 reopens #1032 reopens #1050 reopens #1052 reopens #1069 reopens #1073 reopens #1087 reopens #1091 reopens #1094 reopens #1110 reopens #1115 reopens #1116 reopens #1118 Reviewed-on: https://gitea.com/gitea/tea/pulls/1146 Reviewed-by: TheFox0x7 <95654+thefox0x7@noreply.gitea.com>
